At present it's just the data being dumped from TaxonWorks and re-integrated into the existing front-end (separation of concerns nicely done). In the future we hope efforts that wrap TaxonWorks APIs and tooling, "companions", will evolve to make things look better. For example it would be trivial to wrap AntWeb in TaxonPages (see Github for everything) to get a new front end there, though that software is focused at the Taxon level. Multiple groups are looking to build out similar efforts at the specimen level (perhaps SpecimenPages).
We've recently has some amazing success with previously "unknown" people contributing to our open-source framework(s). These contributions, and hopefully future ones, will let us deliver additional features in a more timely fashion, for example things like multi-entry and "traditional" taxonomic keys. TLDR - there are opportunities to chip in to the "refresh" efforts on multiple fronts.
