To be discoverable I would propose replacing the + sign by an extra line saying "More actions" / "Less actions" to toggle them. Or put that in the preferences.
... but I think that even after the user has discovered the meaning of the (+), putting the (+) in the same menu entry as Open still doesn't quite make sense, since the 2 things aren't related.JosephMcc wrote: Hovering the icon does display the text "Show more actions".
If an extra line of text would take too much space, then maybe a downward-pointing triangle (horizontally centered) that if the user clicks it, it expands into more menu entries. Some GTK+ menus put this kind of triangle at the top or bottom (to indicate that the menu can scroll) when the menu is taller than the available screen space. The triangle is only about half as tall as a line of text.
I also question the concern about screen space, since I think the Nemo right-click menu (when collapsed & often even when expanded) is typically no more than about 500 pixels high, which should fit on most screens, and those scrolling triangles could be added if needed on small screens.
Also, I think standard grammar would be "fewer actions" as the current menu has, rather than "less actions."
I agree that a preferences option would be suitable for "how to expand & collapse the right-click menu," if the Linux Mint developers can't soon be convinced to change the current (+)/(-) icons entirely.
