How To Optimize High Res Screen?

I did the same as always and increased some font sizes here and there.
Increased fonts in the terminal and itunes. Basically anywhere where I need to read the content all the time.
I still set the preview app to icons only because I have clutter. My Opera Windows has tab previews left and only a big long address field on the top. Everything else is website space.
I installed better touch tool and set the Windows 7 like snap to screen feature to my liking. That is very useful.

In iTunes I still miss the old view with Genre, Artist, Album with the titles below. For some reason they removed this a long time. When I used Windows I was a foobar2000 fan. With my iPhone I was forced to get used to this crappy slow iTunes BS.
Anyway I have two columns Artist, Genre and the titles on the right. The whole thing is always full screen and text size is big.

I don't know what else to do. I always prefer focusing on the thing at hand and like everything else in the background. The app I use usually is always full screen. Only finder and terminal is smaller. I was never really used to anything smaller and when I need two things side by side I either use the snap feature or an external screen. Everything else imo just diverts attention for no real benefit.
