Yes, there is a version of CustomUI that works with MoI v4.

If you go to the "Resources" link on the main web page, there are links to collections of the most frequently used scripts here:
I do want to make it easier to browse and install script in the future, I have some ideas on having a script browser that you would pull up in MoI that would connect to an online script repository. It will be quite a lot of work to make that though so I'm not sure when it will happen.
Thanks to you it brightened up a bit :) Although I am still looking around with curiosity at all these "magic" plugins for Blender. It seems that thanks to them you can really speed up your workflow. Plus, easy installation and great documentation are definitely advantages. I have to figure it out somehow, which will be better for me :)
