Regions Add-In for VS.NET 2003
I found this one submitted as an entry to the contest. It's simple, does just what it says it will do, and makes organizing larger code files with regions a whole lot easier. I was doing this recently with the VSCmdShell project and this add-in save me some time. I especially liked the "Add to Existing Region" command you get on the right click menu. Great work Justin!
