What your starting to see is folks, myself included, trying to expand the capabilities of what you can do in the game a bit further. Some stuff works well...other stuff not so much. However, with everything...everyone's mileage varies.
Some things look like they are some effort at first, but in all reality not so much. It simply different from the norm. I get it though, some folks like to keep things as simple as they possibly can which is always their option. I think a core reason for 7.5 users not upgrading to VX comes from the same idea. Even though there are multiple guides all over the place, people have something that works and they probably don't want to risk screwing it up.
One thing I do and I recommend this to anyone testing out new stuff is to setup a separate portable install of the game you can use to test things out your not to sure of. With symbolic links you can even share the activemod folder of your main game with the second install which saves on doubling up on things.
If there is something you cannot get working that you are really interested in put a question out on the threads, or @ mention the modder direct in the items comments. I say @ mention the modder as not all folks follow the content they create. When you @ mention folks...it makes sure they get a notification.
By the way nice job on using TKX Utilities as a Mod Manager...I always knew it had the ability but never bothered to actually set it up. Maybe something you can give the community some tips on how to do.
