Cite source of data, but also indicate who analyzed/revised data (provided in native script, IPA, etymologies, etc.). This would probably be hard to do on a term-by-term basis, maybe indicate all "data-revisers" at the top of the page for each lect?

Trying to add this as a column in the definition of Parameters in datatables.py, so that you can expand an entry in that table to see the CDIAL description. HTML does not render at all there though, just gets showed as raw text.

Committing a new version of the database repeatedly is not good software practice (data updates should be disassociated from the application), and it makes the repo size massive. Figure out how to use Git Large File Storage instead.

• Support regex
• A little dropdown with easy access to Samopriyan symbols would be nice
• Shortcuts for matching classes of sounds, e.g. Ṭ should match all retroflex stops

On the map: different marker shapes for different historical stages (OIA/MIA/NIA), different marker colours for subfamilies of IA (at the level of small agreed-upon groupings, like Marathi-Konkani and Shinaic). In the parameter list, there should be a simple visual showing which clades a term is attested in.

Some etyma have numbered subsections. Group these somehow (columns? collapsible sections?)

I think you should only include clld here:

The clldmpg package is meant to include the MPI SHH "corporate identity" in clld apps hosted on MPI SHH servers.

You probably don't want to link to MPI SHH from the footer of each page or include the MPI SHH imprint.
