vehicle, music, and bot guis aswell please
The wrench menus for standard bricks, vehicle spawns, sounds (aka music), and bots are already supported.
Does this work with the minigame guis like slayer gui?
No, but I'd bet if you opened up the addon and changed this:
$EWL_Lists="Wrench_Lights Wrench_Emitters Wrench_Items WrenchVehicleSpawn_Vehicles WrenchSound_Sounds wrenchBot_Items";
to include lists from the slayer GUI it would work (though the icon might show up over text depending on how the slayer menu is designed).
