I’ve seen this asked a few times but each had some extra situation that I don’t have so I’m going to make a new post.
I use Libre Office for a lot of writing stuff, and I save things just as default odt. I still have the preview icons and sometimes I can go off of those when searching, but they are way too small for me to skim through tons of documents trying to find a certain one. I’m on Windows 10 and Version 18.104.22.168. I’ve already saved almost 300 documents, so switching to a different saving method is out of the question and would take way too long.
