- Improved: While you are browsing tabs by Ctrl-Tab/Ctrl-Shift-Tab, now collapsed tree is automatically expanded, if you stay there with pressed Ctrl key. (You can change the delay via a secret preference "extensions.treestyletab.autoCollapseExpandSubtreeOnSelect.whileFocusMovingByShortcut.delay".)

- Modified: The counter in a parent tab now reports the number of all tabs in the tree including itself.
