I think if it’s about adding an icon next to the cursor, rather than changing the cursor itself, it’s possible to implement that in a clean way here 🤔
I hadn’t really thought about this. I’ll look into it eventually, but one issue is that my pixel- and Command-based hit test is much more expensive in terms of performance than the tile-based lookup that MouseSystemEx does.
That’s fine if the code runs only once per click, but to update the cursor each (interactive) frame, it’s likely a bit too expensive without further optimisation.
I can’t give you an estimate for when this will be available right now. In theory it’s not difficult, but I haven’t been able to work much at all on new plugins or features lately.
