If this was accessible for Voice Over (the MacOS screen reader), blind developers would literally bless you for this. Half of those non-coding, web-based tools have huge accessibility problems, and an efficient and ergonomic interface would be a godsend. I can't test the accessibility aspect myself, now, as I don't own a Mac and I don't work in a team environment, but I can get you in touch with some people if you're interested. The fact that you're doing native and that you're focused on the keyboard means there's much hope, though.
