I have installed Ubuntu onto my parents laptop. They are around their 80s. They manage to remove icons from the launcher accidentally again and again. I have to put them back manually, only to find them removed again two weeks later. Of course they'll swear "they did nothing like that". They also reorder the icons accidentally, so remote support becomes harder, although that isn't nearly as bad.
Is it possible to lock icons to the launcher so the user can't remove them? Just removing the option on the quicklist to unlock the icon would be fine.
Locking its position would be great too.
