Directory Opus has been doing that for decades.

I'm sure it did, but that app looks like a Win XP-era app (not even Win7). FilePilot is fast, looks good & feels modern (support a command palette, fuzzy search, etc). The only downside is that it runs on the GPU and so running it inside a VM is a bit of a hassle.

Why the hell would I want a file manager to be run on the GPU. it's supposed to be light and fast, not a 3rd person shooter.

You can completely customize how it looks.

Hadn't heard that name since the Amiga days and had no idea it was still around!
