Hi there! Cool tool :)

I upen dua i, mark some files using space and want to delete them with ctrl+r.

But, I suppose because the tool is still scanning, I get a Traversal already running notice in the bottom.

I'm not quite sure what the problem is here, but here are some suggestions:

• When user tries to delete, pause the scan and prioritize the delete action. If that's hard, cancel the scan and restart after delete.
• Don't scan (sub)directories where the user isn't in.
• Cache the scan outputs somewhere, so the next time I open dua the scan is already done, for the most part.
