There's 2 UIs - which you can find through Petr's MOI page.

Both of them have have what you are looking for. As Dave said, only available for V1.

I did CustomUI 2 and it was a lot of work so there was no way I was going to keep up with Michael on the betas :-)

I hope to adapt it for V2 after release - but I might make it differently next time ;-)
