This is a very minor thing in the Vault GUI client but I thought I'd mention it. In the the 2.x versions, when you opened a repository a message would appear on the top of the pending changeset tab that informed you that it was scanning the working folders for changes. In version 3, it no longer seems to do this. I liked it telling me it was scanning because most of the time, I only launch the GUI client to do a commit and the message let me know when it was okay to do so.
Also, is there any way to force a scan of the working folders?
