Short rest taking a whole hour is a baseline rule that annoys me.
I think it should be action movie logic. If John McClaine finishes a fight he takes a breather and the scene cuts to elsewhere. When it resumes with him he is moving through the tower looking for more bad guys to fight having pulled some glass out of his feet and ready to fight again. Five minutes to catch his breath, spend some hit dice, and regain action surge or ki points.
He does not hunker down for an hour long siesta before going to hunt the active armed terrorists who are hunting him.
An hour long siesta is not something I expect to happen in most fantasy adventure narratives, let alone regularly once or twice in an adventuring day.
