Previewing when up/down arrowing through the list of files when searching filenames

### Problem

I have too many memes that are categorized by filename

### Proposal

Heya folks, the closer of #1601 here, happy Gregorian calendar reset! 🎉

I wanted to suggest the ability to preview based on cursoring through filename search results if File Preview is enabled. I'm a keyboard jockey, and would love to quickly find memes when arguing on the internet lol

What do y'all think?

Cheers!
