Background:
I got a solution with 117 projects. Oftentimes, I will sketch the implementation of a new subsystem and only partially test-cover it while doing the sketch. Once I'm satisfied with the shape and usage, I switch over to completely test-covering it. When doing this, it's helpful to look at the metrics view NCrunch provides.

However, because of the number of projects, it's a bit tedious to navigate to the right project, open the right namespace etc.

If there was a textbox on top which would represent a filter on project-names and namespaces that would automatically filter the list on keypress (simple matching: if a project-name or namespace contains the text, display it), that would make such flows faster.
