Mostly what I’m trying to say though is I’d like erase to behave more as an exception that I hold a button for and it expects me to pop back to my current tool rather than a tool I hang out on. Maybe I’m an edge case on this, but it’s one of those things that maximizes speed of use which seems to be what the app is doing elsewhere.
I recognize if it always does the springloaded return, it can be less intuitive for new people, but my argument goes if something as ubiquitously accepted as Photoshop can get away with this conditional logic (a long press is springloaded, vs a tap is a tool switch), then Animation Paper could too.
Your call, naturally!
