After reading Scott's post about Virtual Desktop Manager, one of Microsoft's XP PowerToys, I decided to give it a try. Like everyone else I have about a gazillion applications open at once and this little tools sounded like a good way to keep everything better organized.
First off I'll say that it plays well with UltraMon, which is a great.
After using it for the last 30 minutes I think it is very nice productivity and organization enhancing tool. I may come to depend on this one.
Like Scott, I too have a couple of suggestions to make it even better.
