I have been having a lot of fun trying out different Ubuntu flavors (Gnome, Mate, Xfce). They all seem to have their favorite File Managers, but they are quite different!
I mostly need a file manager to search, and secondarily to show ID3 tags in columns. Thunar (xfce) seems unable to do either one, Caja (mate) can search but I cannot find any way to add columns. That leaves Nautilus, with the following plugin:
sudo add-apt-repository ppa:atareao/nautilus-extensions
sudo apt install nautilus-columns
Can I safely delete thunar and/or caja? I have already chosen “Files” as the default manager.
