Crowdfunding the creation of the next version of LFGSS

Weren't you planning something like filtering by tags (instead of fixed hierarchies as with forums and sub-forums)?

We still are.

Those are basically parts of the search functionality that doesn't yet exist.

To be able to say "Only show me Events within a Microcosm"... or "Only show me Microcosms that contain the word 'foo'".

Filters are just a form of search. And we haven't yet addressed search.

Search isn't a really difficult thing, but it can be made near impossible if the structure of the things you're searching keeps changing. So we've punted search out a bit to fix all of the bugs and to allow the core of Microcosm to settle down and stop changing so much.
