I definitely think Short Rests need to be improved into something which is much closer to the pen and paper version. Healing should be based on hit dice, which you can spend one at a time, or use "auto" which spends as many as it takes to get you up to full, Arcane Recovery should be a thing. I don't know if attunement will be in this game, but if it is, short or long rests should be how you attune to items.
Solasta does short rests very well, although I think it has them unlimited, and a limit of 2 or 3 in BG3 would be better.
Solasta also has designated long rest camps, although they might be a little generous (save for the final dungeon which has a ton of encounters with no camps - although the game did warn you that there would be no time for long resting).
I don't have solid opinions on the best way to handle long rests in BG 3, with all the story stuff during long rests. Long rests should recover half your maximum hit dice pool.
