I'd like to see a "rest" button (along the same lines as the digest button). So say, if you're running from a monster zoo into a corner where they can't reach you and are out of view for a while, you can hit Rest and get HP back instead of having to press the space bar once per turn waiting for HP to come back before you jump back in (in my case, it was being near levers that teleported you around, so I could hide out when I ran out of food/healing items).
This is a long and ancient debate (probably the oldest debate about this game ) bottom line they wanted to make regen tied to food, because if there's an instant rest button it makes most food useless. "Digest" is the closest thing to come to that, and even that is pretty recent.
