In my opinion, this is that I want to have most. Customizable spawn menu When I try to load some objects into the scene, I have to load the entire vehicles list. It will be better if you can separate them like, this is spawn menu for objects,sedan,hatchback,truck, etc. Because having all objects and vehicles in one spawn menu isn't very efficient. The spawn menu in Garry's Mod is great, you can assign anything into the list.
On the right hand side of the menu there is a filter list which allows you to sort through which vehicle or object you want to spawn.
