Plug-in similar to Premier Title

Hi All,

I would like to develop a plug-in that shows a non modal dialog similar to Premiere 'Title' dialog. I would like to update the preview in 'Program Sequence' window when user updates the canvas in my window.

Is Synthetic Importer a right choice for this kind of plug-in?
Whether 'Title' is implemented as a plug-in or is it part of Adobe Premier itself?
I noticed that Synthetic Importers are called by two processes - Premier itself and 'ImporterProcessServer.exe'. How to mange my window between these two processes?

Thanks & Regards
Chandan
