Welcome to QuickFolders!Monday February 19th 2018


Premium features are power functions which are an incentive for users to regularly support the QuickFolders project through a yearly contribution, called QuickFolders Pro license. My aim is that instead of very few people trying to carry the project with sometimes large donations to try involving more supporters. It is a lot of work to keep the project going and up to date with all the latest code changes which happen every 6 weeks on the Mozilla code base. Staying in sync with the three applications (Thunderbird, Postbox and SeaMonkey) and to support multiple platforms (Windows, Linux and Mac) and languages and writing support emails and fixing bugs is actually a lot of work. I would rather actually spend more time on this as opposed to maybe 6 to 12 hours / week, but for this it needs to be financially viable.

What Premium Features exist?

Here is a list of Premium features that are unrestricted to licensed users.

For non-licensed users, the premium features can be restricted and, when used, will show a notification bar in order to promote buying a license. I feel this is the best way as it gives you a chance to try them out and get an idea on what other great future functionality will be funded by supporters:

Premium Feature What does it do?
quickMove quickMove Allows moving mail to any folder by entering one or two letters (part of the folder name). This is very useful when we have lots of folders. Drag the mails to the quickMove button and then start typing. Hit ESC to hide the panel. Right click for more options and a list of messages lined up for moving.

With the Premium version you can also use and configure a keyboard shortcut - by default this is SHIFT+M. In Postbox you might want to redefine this to a different Letter as this is bound to "recorded Mark Message as Pending/Not Pending": for choosing an alternative, see Postbox Shortcuts

quickCopy (4.2) quickCopy Same as quickMove, but use for copying mail. Hold CTRL when dragging the mails mails to the quickMove button and then start typing.

With the Premium version you can also use and configure a keyboard shortcut - by default this is SHIFT+T.

quickJump quickJump Similar to quickMove and using the same button, click the quickJump button and type a folder name to go there immediately. hit ESC to cancel. Future versions may use a keyboard shortcut for this.

With the Premium version you can also use and configure a keyboard shortcut - by default this is SHIFT+J. In Postbox you might want to redefine this to a different Letter as this is bound to "Mark as Not Junk": for choosing an alternative, Postbox Shortcuts

Tab Icons Tab Icons
You can now add customized icons to every QuickFolder tab. In Thunderbird this icon will also be shown in the folder tree. The easiest way to do this is using the yellow "Image Icon" on the current folder tab while are in the folder:
Select Icon from Current Folder

To get started, you can download a selection of (16px²) icons here: - these are mostly favicons from websites but also some of the fabulous fugue icon set by These are shared under fair use there I not own or transfer any rights for re-using them.

With the free version of QuickFolders, the number of icons is restricted to 12.

Line Breaks Line Break
You can now insert a line break before any tab in order to show another row of tabs. To remove the line break, you right-click the first tab in the line and select QuickFolders Commands > Remove Line Break
Separators Separator
You can now insert a separator before any tab in order to indicate a new group of tabs. To remove the line separator, you right-click the tab to the right of it and select QuickFolders Commands > Remove Separator
Tab-specific Properties advanced Tab Properties

This powerful feature allows you to determine specific exceptions to invidual tabs: You can hide its unread status or mail count (which might be helpful for draft and sent folders) set default mail addresses and add other specific features such as a different palette or customized colors. For a customized background I highly recommend using a linear gradient CSS rule - for your convenience I added a link to the Ultimate CSS Gradient Generator from Colorzilla. Simply click the button beside the text field to create your own gradient and then insert the W3C specific rule e.g. linear-gradient(to bottom, rgba(30,87,153,1) 0%, rgba(41,137,216,1) 50%, rgba(125,185,232,1) 100%)

Setting default To Email address and From Identity for creating new mails when in a folder makes it easier when we store email from different identities in the same mailbox (e.g. Local Folders). For example: You can now configure your desired sender identity for each of your mailing lists. Or select a default recipient for when you write a new email from a folder.

Reading List  Reading List "Reading List" Icon for storing bookmarks for important mails. Drag an email to this button and QuickFolders remembers it for you, without having to keep a mail tab permanently open.

advanced Tab Properties

Hold down SHIFT while clicking to open a new window, and hold CTRL to open a new tab for the email. Right-click any entry you want to remove.

To test drive this feature, the free version allows adding up to 5 of these.

Folder Tree Use the new folder tree shortcut [F9] in order to hide / show the folder tree
Create Child Folder [Bug 26150] quickJump / quickMove - create child folder command [Thunderbird / SeaMonkey only]. Enter parent folder name (or partial) then press slash [/] to type child folder. See this video for a detailed demonstration.
... More premium features will be added over time - you can also request new features here...

Other Benefits of having a Yearly License

You know that you support the project and that the development and support will be continue. There is a huge amount of work involved not just programming and keeping QuickFolders up to date but also supporting users, coming up with better ways of doing things, fixing bugs, and keeping QuickFolders usable across various platforms and host programs (at the moment we support Thunderbird, SeaMonkey and Postbox). I am constantly helping people with using QuickFolders and their mail program and how to get the most out of email on the desktop.

The donation screen (which is normally shown after an Update) is hidden.

Alternative Monetisation Models

There are quite a few software developers (and also some users) who believe that software should generally financed by advertisement or even by selling user information. I am firmly opposed to this way of making money as it impacts both productivity and privacy rights; also in the world of Email I would find this way of generating value deeply problematic - even if it was strictly opt-in. There is a lot of personal information in our daily mail and a lot of knowledge that is being stored and retrieved with this powerful tool.

One of the reasons for a personal Email Client on the desktop is the fact that we can store our data on our personal hardware and use it any way we like. On the other hand, if we use a web mail client (like gmail) we can never be sure whether the information is used otherwise and whether we get targeted with distracting information (be it by injecting advertisements or via targeted advertisement emails) - it is one of the goals of any mail desktop client to eliminiate these distractions as much as possible, and focus on one thing only: managing communication.

QuickFolders is an especially powerful set of tools to harness this information and it will evolve and keep saving time and make your experience of mail more meaningful and intuitive.
