Because screen space is precious (even with more than one monitor), I occasionally have other toolbar windows pinned or overlapping the NCrunch Metrics. Switching back to the metrics, however, forces me to reopen the tree back to the level that I had it prior to switching tools. It would be a nice feature to have it automatically remember what the tree expansion was before and to re-expand the tree when I switch back.

Great product by the way :: )

+1 for this suggestion. I do most of my development on a laptop. The NCrunch Metrics and Test windows are almost always unpinned, and I loose focus all the time, so remembering the layout would be fab. In addition, I'd like to suggest that there was a "Go to Test in Test Window" and "Go to Metric in Window" options from the tests menu.
