Yes, I want add new options in the future for advanced operations like export/import selected widgets. Maybe I can add this to empty space.
But I got one idea how to deal with help button. I can remove help button from second level and can create small floating button on top of the dialog in space between 3rd and 4th column. Button will overlay with first half on “align top” button and with second half on “align to width” button.
Or maybe without complication I can place it to top-right position on every level.
This can will be applied for both levels
something like this :
I can add aspect to GUI
