Feature request: Pause Queue

I regularly find myself in the situation that I'm working with ComfyUI and something else (eg. work related) comes up and requires my attention (and my PC's processing power). Now I always have to clear the queue, do whatever needs doing and then have to write the prompts I was trying out and queuing AGAIN, if I can even remember what all the stuff I was trying out actually _was_.

It would be great to be able to pause the queue after the current run finishes and then just resume it after an arbitrary amount of time. ComfyUI should clear all locks on VRAM on pause (so you can actually DO whatever you wanted to do; maybe this could also be a setting for the user to choose) and restart from scratch when the queue gets resumed.

Basically it's an extension of "clear queue and resume later" without the need of re-configuring everything you had queued.
