I love the concept of GridMove, seems to work good and I have a suggestion that would pretty much guarantee I would use it permanently.
There needs to be a way to tie it to different profiles. I use terminal services at work and some users have one screen, some have two or three screens. Each of the users should be able to change the settings in gridmove to their own preference. But the way it is now, if one user changes settings, everyone else gets hosed.
I think the ini file should just be moved from the program files directory into each user's application settings directory and it would take care of it.
