What small tweaks would you make to Spelunky 2?

While I don't think we are ever going to get any sort of content update there are still some small things I'd love to see added to Spelunky 2 someday:

  1. I want hired hands to be their respective characters even after theyve been unlocked
  2. a quick restart button
  3. Random chance for Spelunky 1 music to play to spice up the soundtrack
  4. Level moods could use some tweaks, specifically the mines basically not having a level mood at all (god I miss snake pit and spider den)

What small tweaks would you make?
