In my opinion, SH3 Commander should be up and running BEFORE even any super mod, it's a vital piece of software. As said before, you ask how to change something you don't like and everyone will say Commander.
Secondly, regarding GWX Gold as I don't think your question was answered, you can download GWX3 Gold and install that without having to get older versions. GWX 3 Gold is standalone, nothing else needed. It even has JSGME included which will give you access to firstly, the GWX optional extras like open hatch, icons, extra campaigns, and also other mods made by the community. Personally, after a recent revamp and reorganisation I've now got, on top of basic GWX and Commander, 44 (!!) mods on my install. It's great, if not a little long to load, lol. I drink much coffee. Just check my sig for what I think are the most important ones (they wouldn't all fit...), and use the search function to go find em. They can be a little hard to track down through the forum downloads and the plethora of file hosting sites people use but we all enjoy the hunt here..
Finally, just in case you don't realise, you won't be able to install WAC and GWX on the same install, they are not compatible so do a search for MultiSH3 so you can get the best of both worlds on seperate installs.
You can PM me anytime if you want any help as I'm here quite a lot, lurking, at periscope depth........
