Hello,
Concerning the floating black tool bar that shows up when text is selected, it currently has only 5 functions (Highlight, Underline, Strike through, Copy & Edit text-images).
My requests:
1. Kindly make it customizable, so that users can add whatever buttons they like.
2. Especially, make it such that users can add anything from 3-5 highlighters of different colors, so that I will not have to go through the tedious task of changing the color of the highlighter each time I want it changed.
3. Kindly allow the "Add note to text" icon there either by default or as part of the customizable item.

I just figured out that a user can disable/enable it by checking or unchecking the feature from Edit>Preferences>General>Show quick actions of text selection. That is very nice to know!
