Absolutely love your product and use it quite a lot but...
When selecting a shape for editing, IMHO it would be much more intuitive & ergonomic if the edit-menu popping up would show all text-related buttons / commands as a group and would not mix text-related with shape-related buttons / commands.
Currently the ‘text color’ & ‘text highlight’ buttons are positioned on the right of the ‘shape border’ & ‘shape fill’ buttons, while ‘text font’, ‘text size’ etc. are positioned on the left.

Maybe it’s just me, but I can no longer count the number of times I hit the wrong button or had to move my mouse back and forth when changing text format...
Not sure if there is some copyright pending on this 🤔, but eg. word processors and email clients typically group them. Customization of the edit-menu like offered by some platforms would be the cherry on the cake, but very much nice-to-have.
