Good job, Mike.
One thing that would be a good enhancement would be to be able to widen, or especially lengthen, the application's window. My screen is tall and I use a pretty high resolution, so if I could make the window taller, my plan would in many cases fit in one screen without scrolling. I'm not suggesting you eliminate the scroll bar. But if a user could have a variable sized window, then the plan frame and the scrolling time frame could also be longer.
Two small problems?:
I for me that when I load the profile, I don't get the right filters. I load the "Active Profile" - see PlanZ.png.
Also, having loaded a profile, if I try to load a profile again, I get an unhandled exception error - see UnHanEx.png
Edit: I also have attached the ActiveProfile.xml file so that you can play with it. Perhaps mine has some construct that's different from the ones you've been building Planalyzer with. Just rename it .xml if you need to.
