Why free form writing tools in separate hierarchy.
To use writing pen option I need to take two steps, then if want to highlight something then tap on DONE then again select highlight tool.
Or if I have to undo the writing then also tap on DONE then do undo then come back tapping on free form writing tool.
If all the options can be in same bar- highlighting, writing tools, eraser, undo, marker tool, rectangular selection tool. it would be less cumbersome and efficient and maybe then use eraser tool on highlighted text to delete highlight as well.
