Add simple category/folder selection for 4K Stogram.

I just recently purchased 4K Stogram. I propose to add a simple category/folder selection for 4K Stogram on each first download prompt, similar to how Free Download Manager 5 does it. This would be useful to separate content that is not related in both a category and its own path. For example, photography accounts from regular contacts, from Film, and from dog related accounts. Thank you!.
