I've used two house rules that worked well for short-rest/long-rest balance.

1. Double all short rest abilities, and let them have the original amount back on a short rest once per day.

2. Let everyone take a short rest whenever they want outside of combat up to twice per long rest. No time limits, and everyone takes them on their own. So there's no "should we rest here?" discussions. If someone needs some resources back, they just state, "I'm using one of my rests." This is my favorite solution.
