Sober,
In case you want to correct links for this thread.
Post #1 mentions NewUIs_TDC_7_5_0.Test version 12 is the latest I have seen. There is a Page TDC update for versin 12, too.
Post #2 still has download links for NewUIs_TDC_7_4_2.
I know test version 12 is buried in the multiple UI thread.
Here is a link which has the direct download links for main New UIs for TDC 7.5 and the page update.
