Purchased ModernMix right from the get-go, seemed like a perfect fit for me and turned out to be such. Started to get picky over some Win8 apps but realised I cannot really pick Win8 Reader over other PDF readers like the one from Adobe and so on, even with the current version of ModernMix just because I can't open multiple windows with documents at the same time.

What I'm trying to trace is it would be a great addition to this particular software if it allowed to open multiple copies of an app. Please take this into consideration, it can be a very proficient feature.
