Linux-only settings, good catch! Could you please attach a screenshot so we know where in the order it should go?

Could you also check (perhaps in the code) if there are any more Linux-only settings that exist?

 Issue 625012  has been merged into this issue.

In Options, this checkbox is the last item in the Appearance section, below "Always show the bookmarks bar".

Re other missing settings: this is something we need to do and track in an organized manner, for all platforms, for all aspects of Options, preferably on a per-section basis by people who are familiar with those sections.

MD Settings: add "Use system title bar and borders"

Also, shuffle around how some strings and logic work. We really only
support removing window decorations on desktop Linux.
