[Feature] Threaded Background Saving

[amcolash]

Hello, I have been using LightZone for quite a while now with my raw files and it is great to use! One thing I have noticed that severely limits my workflow is waiting for the saving dialog (when returning from editing a photo).

I have looked in the source code (I am a developer!) and it looks like the saving progress thread waits for the operation to complete before the UI returns to the browser. I was able to hide the saving dialog while it was happening, but it looks like the ui is still waiting for the status to resume.

What I am proposing is allowing for that saving thread to run in the background (possibly no saving ui if you autosave) and immediately switch back to the browser and potentially begin editing another one while the saving is still occurring. A potential issue could be that there is not a cancel button visible (unless it was added elsewhere). I am unsure how tied saving is to the ComboFrame, but it seems like this could be complicated.

I am curious if this would be at all feasible. Thanks much!

I think this is a nice idea. :+1: I'd like look into it when I have enough time, but I'm currently busy to work on other new features. I'd greatly appreciate it if you could help us to implement this "background saving" feature.
