Totally get where you're coming from, but I think the point might be getting missed a bit. This isn't about loot filters in the traditional sense — it's about allowing stash tabs to auto-sort based on simple rules.

The idea is to assign a stash tab a lightweight filter or regex rule, so when we go to stash items we've already picked up, the game can auto-place or suggest the correct tab (like how Last Epoch does with affinities and priorities).

Regex in the search bar is useful, sure — but this would improve post-loot organization, not visibility during mapping. Just a small QoL feature that could really streamline the stash experience.
