Have you tried Edit->Text Tidying? Also, what about the “remove trailing whitespace from documents” in the compile window (right side, under the gear icon)?
Yes I have. Edit->Text Tidying->Remove Empty Lines Between Paragraphs works on only one document at a time, and by ‘bulk’ I meant multiple docs, or ideally the whole manuscript.
I have tried the trailing space option too but this only removes blank lines at the end of a doc, not within (as the name of the option implies).
