I have upgraded my Touch Diamond 2 to WM 6.5 (great update BTW) and I admit I love the Titanium plugin :simple and nice ! I even have temporarily disabled the HTC Sense plugin !
Now as a developer I would like to develop a plugin for it and for example for ProjectXT 😉 . I know it is possible because there are some in XDA-Dev. In fact, I will have to look there to understand the XML files and registry needed for building a Titanium plugin.
At the same time I’ve searched for an official word concerning Titanium for developers and I get it :

I couldn’t agree more with the two answers after the official one… :/ Wake up MS ! 🙂
