Before I buy the full version of DisplayFusion, can you please confirm that it will do the following?

I have 4 monitors in Portrait mode, A B C D.

I would like to know if DF can help me with maximizing one application over monitors A and B, and another application over monitors C and D. I would really like to maximize the application between the two monitors since at times the applications will snap back to a single monitor and have to resize and position the window again.

I know the free version of DF can span across all four monitors, and I love being able to open Excel 2010 across all four, but I do not need a four screen view of Outlook 2010. Even if I have to customize it via a hot key I am okay with that. Its better than manually resizing and positioning the application everyday.

Thanks for your time and assistance.

Yes you can do that with hot keys. I did a search of the forums and found a post that showed how to setup hotkeys to do what you're asking and I'm using them right now successfully. Very usefull
