Thanks! What features would you like to see implemented?

Probably a plugin system for datatype => renders/editors. ex: (numbers, datepickers, select, checkboxes, etc.)

Ah, that's something I would very much like to implement. Probably only in '21... More pressing stuff first.

Until then, have a look at Jexcel, it implements numerous pickers/editors (not all of them mobile-friendly I believe).
