Run $ sudo apt install alacarte
$ alacarte(Don't type the $'s, that just means you aren't running as root.)
This menu editor has no advantages over the default one except that I know
the terminal command for it.
Now let's add this menu editor to the menu so that we don't have to use the
terminal to access it in the future. Within the menu editor, click 'Other',
and then click 'New Item'. For name type 'Menu Editor'.
In your menu, under 'Other', you should now see 'Menu Editor' and can now get
back to this window from there.
