Store the queue on disk, reload after crash

[42degrees]

I get video card crashes occasionally (usually about 1 per hour). The annoying thing is that I lose the entire queue when this happens (besides having to reboot the computer). I assume that the queue items are JSON blocks and further assume they are only stored in memory currently. If either of these assumptions is wrong, I'd love to hear about that. Otherwise I'll try to find some time figuring out where the queue is stored and trying to move it to disk. This would also probably indicate a need for a configuration parameter to say where the queue is stored. Also a button to restore the queue from the saved files.

Thoughts?

We really need this for things like FILM VFI that kills the whole ComfyUI process regularly.

Did this ever make any traction? This feature would be immensely useful

Implementing it is a bit beyond my current skillset.
I wouldn't assume it wouldn't be that hard for people who are familiar with Comfy code to move the queue data so it can be persistent.

I'll often queue up a bunch of things at night with long render times like upscaled AnimateDIff or SVD hoping to see if changes are for better or worse etc. A lot of errors will just jump to the next queue item which is great.
Other things like Frame Interpolation seem to kill the whole process and the queue is lost which is extremely frustrating.

Really hoping someone else with familiarity can move the queue data to place that would persist after the process is killed.
