Ok LibreOffice, Opening a file read-only means I don't want to be allowed to save it. It does not mean that I do not want to modify it at all. :facepalm:
@fc501b69 Sorry, disagree. Read-only means "read only"...not write/modify. I've run into this situation as well, and I get it's irritating. So maybe an option to "allow modify" and only allow "save as..." (as usual), but nah, if I open something as read-only it should only be readable.
