I see 8 out of 195 "unknowns"which seems to be pretty good coverage. The remaining unknowns are things like serial verb constructions and reduplication, which are very uncommon in European languages. I'm not sure why these are uncoded but based on my knowledge of the methodology for Grambank it's possibly that these typological features aren't mentioned in any source. I agree it seems like these should be straightforward to code however, I'll ask someone
