I stupidly chose to uninstall Nemo again and try to live in Thunar for a week… turns out I vastly prefer Nemo but stupidly I had hidden the icon in the menu (Whisker) because it was still showing after uninstall.
Now I don’t know how to make it visible again?
do you have nemo.desktop file somewhere?
sudo updatedb
locate nemo.desktop
I don’t have those commands; what package are they from?
mlocate
/home/bgeek/.local/share/applications/nemo.desktop
/usr/share/applications/nemo.desktop
Strange … It should show up…
What exactly have you done to hide the entry?
Maybe Symbol (Icon=folder) is delete in nemo.desktop?
Also look for/in autorun-autostart.
~ >>> cat /usr/share/applications/nemo
nemo-autorun-software.desktop
nemo.desktop
nemo-autostart.desktop
~ >>> cat /usr/share/applications/nemo.desktop

But it is just a shot in the dark 
Right Click on the Nemo icon in Whisker Menu and chose “hide application”
It still works, I can set it as default file manager so clicking the File Manager icon opens it. It also appears to still run with the - - no-desktop flag as I set it before hiding it.
May you can unhide with menueditor
menulibre
Ah. The obvious solution.
Weird that I could hide it without it.
Off to install menulibre
Hy,
In my case, if I want to unmask applications in the Whisker menu, I delete the ****.desktop inside this folder: /home/myUser/.local/share/applications/
