I would like to be able to maximize a window across two monitors but not the third. It is super useful when I am working in Excel and SSMS for data comparisons.

I was looking through the advanced features and could see a lot of useful stuff for maximizing on X, Y, or Z, but not both. I realize this could be a nightmare to code since each monitor is it's own device with a variable size and such, but if it does exist please enlighten me. If not, add it to the wishlist.

Cheers.
