Adding new filetypes to database (user customization)

[Tokariew]

Hi is it possible to add new file extension to filetypes.yml without copying and modifying the whole list?
I tried to create filetypes.yml and added extension what i feel i'm missing, but then vivid only generated colors for new extensions…

Thank you for your request. That is not possible right now, but I agree that it would be very helpful. Some kind of "overlay" database that has a higher priority than the builtin one, if I understand correctly.

Yes something like overlays
Or if used yaml interpreter support merging keys maybe use it?
