Feature request: Sort downloads into folders based on various criteria

[ghost]

Love the add-on and was wondering if something like this is possible at all. Looked around a bit and saw a few old sorting add-ons, and while I'm still on FF that allows those add-ons, at some point I too will update to 57 or newer.

So what would you think about a feature that could sort downloads to either entirely different download folders, or subfolders of the main download folder. I'm specifically thinking about sorting based on domain for example, but naturally other filtering would be cool too.

Thanks for your time.
