took some time to clean up the UI a bit, mainly unifying row size. also been very inspired by linear/supabase recently for UX stuff and added in linear-style row selection to clean up the little "x"/"c" buttons. now you can select rows, delete them with delete, or duplicate them with cmd+d. it all just works. oh also there is undo/redo! im using the giant cantata depot file here (~3MB), loads almost instantly and no lag in the interface for scrolling/operations/etc.
