Changing file extension from “melodymodeller” to “capella” was quite a good move (better one would be to restrict it to just four letters at most, e.g. cpla, or even three - cpl, keeping possibility for adding some ‘x’ at the end, e.g. cplx, as it’s quite popular nowadays (xlsx, docx, eapx, etc.)). Continuing this trend, could you remove “Blank” wording from diagram names/types perhaps?
