Would ya believe it, I've entirely re-written this mod yet again. It's only been a year since the last version! This one is a big, huge, gigantic change, and unfortunately some of the tweaks from the previous version have to be left behind due to how they work. But on the bright side, there's a whole host of new tweaks, of which I'd argue are much more essential tweaks!
I'm not gonna bother with a changelog since I've updated so much that you'll just have to see for yourself. I didn't implement any kind of save importing, so you'll have to set up everything again, but that shouldn't be much of a problem!
Of note: You use "mmtmenu" in the console to open up the menu now. Also, the menu system works in multiplayer now! There's even a functional loading system for multiplayer, so you can carry over your settings when joining a server without needing to fiddle with setting it all back up.
I might plan a v5.1 to include some of the missing tweaks since the last version, and to fix any bugs that are reported. Otherwise, enjoy!
