@BPerlakiH Thank you but:

• Can you please update the changelog (have move the tickets to 3.3.0)
• Not sure what you have done actually, so I guess basically there is no impact beside fixing the problem. Is thatbright?

I don't know if it's bright 😀 but it's in the PR description: Re-arranged the buttons, so no long press is needed to access them

• Random is moved outside of bar to go to top, next to search
• tab icon only reacts to single-tap and displays the tab list
• library icon is moved from menu to bar and avail on single-tap
• menu icon is added (we now have 7 icons instead of 6) and serves on single-tap what was on long-press-tab-icon

Bookmark icon used to work with single-tap to list bookmarks and long-press to choose to either see bookmarks or add one. That's another hard-to-guess behavior but I #695 fixes it by removing the long-press and having the bookmark-this page action inside the bookmarks drawer

LGTM from a user's standpoint although I haven't tested it. @kelson42 does that look OK to you? Do you want a testflight build with those two PRs to test it live?
