Have a panel that shows info and keyboard modifiers for the current tool
All Adobe applications are quite complex beasts, and what all the tools do and particularly what holding different modifiers or keys do can be quite arcane.
I imagine a panel you can have open on the side, and it will show information and the modifier options for the currently active tool.
For instance for the Star tool, it can say what Shift, Option and Command keys do, and that you can press Arrow Up and Arrow Down to increase the number of points as you drag.
Pro users can keep the panel closed, but it can really help new users who want to discover the full power of the tools.

Yeah. Like AstuteBuddy for AstuteGraphics tools, but better — show modifiers before the mouse key is pressed and not after. And may be make the helper float near a cursor and not as a panel (which is tough to remember to open). Or you can expand the 'Show' filed in the bottom that you have. See how your competitors do it, CorelDraw and Affinity Designer.
