Accept multiple root taxa and/or filter function to fine-tune listed observations

As hosted on https://imerss.github.io/galiano-bioblitz-2023/Molluscs-Reknitted.html# we have a fine display of Molluscs but @chlorophilia has noted that we really need to restrict this to marine taxa as per the project remit. This is not an easy proposition informationally and is currently done in the data workflow by laundry lists like the following:

What would possibly be most helpful would be if in addition to the root taxon, the app could accept a filter function to exclude any unwanted taxa in a freeform way. I appreciate this would be somewhat complex since it would disrupt the paging functionality which can currently be done at the iNat API level - any ideas?

Hey! Sorry I still haven't polished off the new version yet. It's very close, I've just had little to no time for any open source work recently due to my day job spilling over to my evenings.

Yeah, exactly, that hits the nail on the head. But I think it's certainly doable - for the first 3 tabs at least. I could rig it up to continually request a page of data from the API, apply the filter, then if there still aren't enough items returned, request the next page and so on. That'd work for the first three tabs: recent observations, common taxa + favourites, but I suspect it may not be possible for the fourth "summary" tab. I'd need to re-examine that but my hunch is that that tab won't be feasible.
