Horizontal Tab Bar Shrinking Issue & Custom Tab Width Suggestion

Bug Report: Horizontal Tab Bar Shrinks Unexpectedly When Collapsing Tab Groups

  • Issue Description: When using Horizontal Tabs with a large number of tabs open, expanding and then collapsing a tab group causes the tab bar container to shrink improperly. As a result, the entire horizontal tab bar becomes progressively narrower. This behavior is very disruptive during daily use.

Feature Request: Allow Custom Pixel Width / Slider for Minimum Tab Width

  • Current Limitation: Currently, Brave only offers four fixed presets for minimum tab width: Small, Medium, Large, and Full Width. Options like Small, Large, and Full Width are often impractical because users have varying screen sizes and workflow preferences.

  • Proposed Solution: Replace or supplement the fixed options with a numerical input field or an interactive slider. This would allow users to fine-tune the exact pixel width that fits their setup (for instance, an ideal width of 88px, which sits right between Medium and Large).
