I think that the biggest problem with short rests is that they have too much scope. Not every "encounter" ability should key off of it.
Take the fighter for example. Make abilities like Action Surge and the maneuver dice recover a minute after using them--fights aren't going to last 10 rounds, so they aren't going to get spammed--and Second Wind can take an hour.
Divvy abilities up by those you can use every fight, once per rest, and once per day.
