Honestly, I really like my MBA and while Yosemite isn't that great in terms of battery life compared to Mavericks, it isn't that bad. The UI looks nice. That being said, one thing has been annoying me for quite some time. Open any app. Example: Safari. Open any other app. Example: Calendar Have a lot of apps opened: Chrome, iTunes, Excel, Spotify, etc. Why is it that OS X acts retarded are never fully makes all the windows the exact same size? Each one has a is slightly cut off at the bottom (there's a tiny gap between the dock and the window. The thing is, its often different for each app so even if they are small, each one makes it look super weird. Its a hassle to go to each app and resize it so it fits perfectly (no space). When I click the green button, it just opens the app to full screen mode which isn't what I want. How do I get OS X to just make all the window sizes the same?
