Idea for a regex based stashtab. Possible alternative to the waystone stashtab.

I'd love to have a large stash tab that you can set an affinity to, similar to a regular stash tab. But here's the twist: it would have child stash tabs that act as filters using player-defined regex on the parent tab.

These child tabs wouldn’t store items themselves—they’d just show filtered views of the parent tab, based on the regex you define.

For example, I’d use it to make a useful waystone stash tab, but I’m sure others could find all kinds of uses for it.

Visually, it could work like how folder stash tabs are currently organized.
