Thank you for letting us know.
"What features do people actually want?"
Well, I would say everyone's taste differs. If you ask me, here is my list (see second half of that post): https://www.speedsolving.com/forum/threads/programmers-wanted.53140/#post-1081902
"What should we focus on first?"
If you ask me, I'm gonna say simulators for other puzzles. At first WCA puzzles such as Square-1, Megaminx or Pyraminx, but that is only my subjective opinion.
As for NxNxN cubes, I haven't found yet a perfect simulator (for me) of 2x2x2, although Werner is pretty close to it.
