Great point @Gaiden2007 — welcome to the community! 
Totally agree — as both a buyer and a seller on Fab, it would be incredibly useful to have a way to filter out owned assets, or at least sort them down. Especially when you’re actively building and want to focus only on what’s new or missing from your pipeline.
While Epic hasn’t rolled this out yet on Fab’s front-end (and I hope they do), we ran into a very similar clarity problem inside Unreal projects — especially in larger teams or solo devs juggling 100s of assets.
That’s why we built Asset Optics — our plugin lets you:
Mark which assets are used, unused, or incomplete
Tag assets with comments or checklist status
See everything on a synced web dashboard so you can filter and sort what matters
It’s kind of like “Fab filters,” but for your actual project content — we wanted something that would help us reduce asset clutter, streamline production, and avoid repeating work we’d already done.
Hope Epic brings better filters to Fab soon — but in the meantime, we’re trying to bring that same clarity to your content browser.
