“Ever notice when you click the +/- icon next to a folder (or double click on a Solution/Project file), it collapses that particular node in the Solution Explorer... but not any of the sub-nodes? If you have a really large project with a deep hierarchy, wouldn't it be nice to be able to recursively close all of the items beneath a current node so when you expand it again it doesn't re-expand everything below it? Now you can.”

Excellent. (The other features of Solvent are cool, too.)
