Great tool. I was thinking of developping such a tool when I found yours !
It helps me managing several projects with process moving from orignal ones by a sode effect of "method amelioration" meetings.
I now want to apply some ggod improvements from a project to another one. The Diff function is great, but using the export/import process is a bit heavy when just a little diff is detected.
I wonder if it could be possible to allow direct edit of the WIT. It can be from the diff tool, a custom editor in the app or maybe open the process editor from TFS Power Tools...
