Well, as long as these keys work as intended, there is no real need to remove them. The problem is that they misbehave and now there is no trust. Speaking of usefulness of these… I do not use them, because I rarely change them on the fly. I know AG use same approach, but they switch modes, ways a tool work. Here with Axo these buttons switch options, not modes. I personally would disable hotkeys (and even buttons hints now say nothing about keys).
When do you plan to release the next beta then?
