Feats need quick filters

Please, browsing the Feat list is only getting worse and the tags are atrocious to navigate.

Add buttons along the top of the page:

1st Level | General | Fighting Style | Epic Boon | Legacy

All but Legacy lit up by default, or all but Epic Boon and Legacy. User can click to toggle each between color (lit up) or grayscale. Or whatever visual language you're using these days. Page is filtered based on selected buttons.

* "1st level" could be replaced by "Origin", but then you would also need an "Other" toggle for Dragonmarks, Dark Gifts, etc.

These categories don't actually exist in the underlying code yet.  It's why we can't create Homebrew versions of specific feat types, only General feats then limit them.

I'd imagine this is part of the rebuild, once they have feats categorized dynamically, instead of hardcoded lists.
