<b>Release 6.15.1</b>

QuickFolders has been fully modernized for 2026, with a refreshed user interface, improved usability, and enhanced theme support — making your folder management faster, cleaner, and more intuitive than ever. Try the new <b>Thunderbird Tabs</b> theme for a fresh, minimalist experience.

<b>Improvements</b>

<ul>
  <li>Flat Style improvement: the active folder now highlights with the user-assigned tab color (if set). You can revert to the original behavior in theme settings <a href="https://github.com/RealRaven2000/QuickFolders/issues/646">[issue 646]</a></li>
  <li>Redesigned themes: Native Tabs and Pushbuttons refreshed with new layouts <a href="https://github.com/RealRaven2000/QuickFolders/issues/643">[issue 643]</a>
  
  After -moz-appearance layouts were deprecated many Thunderbird versions ago, we needed to come up with our own style rules that integrate well with modern versions of Thunderbird. Accordingly, <i>Native Tabs</i> was renamed to <i>Thunderbird Tabs</i>. 

	While supporting dark / light themes it uses the same highlight color for the active tab as Thunderbird.

  The minimalis <i>Pushbuttons</i> theme  uses slight rounding and outlines, highlighting the active button with Thunderbird’s primary accent color for a subtle, elegant touch.
  </li>
  <li>Toolbar icons now reflect the main theme colors instead of using hard-coded values, improving consistency especially in custom themes <a href="https://github.com/RealRaven2000/QuickFolders/issues/655">[issue 655]</a></li>
  <li>Improved theme handling: switching themes now resets layout rules for full fidelity <a href="https://github.com/RealRaven2000/QuickFolders/issues/650">[issue 650]</a>
  
  Previously "stuck" CSS rules made switching between themes unpredicatble addEventListener would often require restarting Thunderbird to see their real effect.</li>
  <li>New Pro feature: show the account name of the current folder instead of the QuickFolders label <a href="https://github.com/RealRaven2000/QuickFolders/issues/648">[issue 648]</a>.
  This can be configured in advanced settings under Miscellaneous</li>
  <li>Custom icons in the folder tree are now automatically resized and no longer cropped when too large <a href="https://github.com/RealRaven2000/QuickFolders/issues/619">[issue 619]</a></li>
  <li>Added an option to temporarily switch to the Basic version after license expiry without losing your license. The license key is backed up locally and can be restored later <a href="https://github.com/RealRaven2000/QuickFolders/issues/652">[issue 652]</a></li>
</ul>
