We occasionally see revision-suggestions for documents (usually from our attorneys) where removed content gets color coded and has a strike through it. Added content also gets its own color coding.
I had always presumed that some specialty software was used to achieve such versioning effects, but one of our salespeople just received a document from their customer and it seems to be in that "mode".
When he tries to delete anything, it simply turns lime green and gets stricken out.
Is this a feature that can get turned on/off in Libre or Open Office?
If so, where/how?
