How can I only show pigments to non-.txt files?

[klaurence]

I think it has something to do with "Supported Filetypes", but I can't think of anything to indicate "everything but not .txt files". I think it has something to do with "!(.txt)"? Is there a way to do this, and how? Thank you very much!

It looks like this package doesn't support regex in that field. Someone will have to add that or add an Ignored Filetypes field.

I think the code is around here.
