How can I disable or remove application comments from the "favorites menu" on Mate? Or remove them completely from Mint?
There is an option for disabling comments from "all applications menu" but not for "favorites menu".
The comment is taken from the corresponding
.desktop file. These files should be either in your
$HOME/.local/share/applications/ folder or in
/usr/share/applications/. Just edit the
.desktop file of the program whose comment you want to remove and set it's comment field to blank. For example:
$ grep Comment= ~/.local/share/applications/firefox.desktop
Comment=Browse the World Wide Web
So, open that file with your favorite text editor, and delete the comment so it looks like this:
That should remove the comments from your menu (and all other places where the comment might be displayed).
