Release notes



+## 1.16.5

+* "New Tab" (Ctrl+T/⌘T) and the tab bar [+] button append the tab to the right edge. Previously it was inserted next to the active tab.

+

1.16.4

• Context/button menus use a popup window if they would otherwise have to scroll (e.g., "Dark theme:" in Preferences and "Folder:" in the bookmark editor).

• Improved tab closing order: close all sibling tabs opened from an origin tab before switching back to the origin tab.
