Undoubtedly would take an immense amount of work, would be incredible to be able to edit floating menu parameters (size, spacing, icon/text placement, etc.) by clicking and dragging rather than adjusting the number of pixels or percent. Perhaps some kind of "Editing Mode" where one can see what's being changed in real time. Just a thought.
Would be nice but won't come to BTT in a general way unfortunately. The dynamic & responsive behavior make it impossible for me to implement.
I have thought about a very basic way to arrange items by dragging, but only for menu's that use absolutely positioned items without any responsiveness.
I think the biggest thing that will soon come to help with creating & editing floating menus is the AI integration.
