Save selected JSON keys when reuploading

[anig1scur]

Thanks for your great work!

Every time after reuploading my json file, the selected keys lost. And I need mannually choose them again...
I'd like if there's a way to hot update json or keep selected keys?

@anig1scur good idea. I'm working on the last session autosave right now.
