I get where you're coming from, we often have someone die just after combat because a heal/potion can't be clicked fast enough (or is miss-clicked). This usually results in some yelling, laughing, and a resurrection scroll being used.
I wouldn't mind some kind of (optional) "pause/one-more-turn" mechanic after combat, but I don't think it's going to be implemented. I just accept it as part of the fun and part of the tactical play to avoid being on fire and low health at the end of combat.
