Not sure this is what you are looking for, but i have an old repo in backups still here
Some links & ressources might be broken btw.
Anyhow, perhaps you might consider switching to Emy by now.
iUI hasn't been supported since 2012, and what i coded to be iUI 0.5 wasn't "acceptable" and become foundations to Emy 1.0.
If you're used to iUI, you should quickly feel home using Emy.
