(Not really sure which forum section to put this in really as its more of an open discussion on general UI methods) In OS X, there is the single menu bar at the top of the screen which switches its content between whatever window is in focus. On MS Windows (and some Linux OS) the menu is attached to the top of each window. Both work fine in principle. I admit that before this iMac (27) I was nearly always PC based, so am very used to the Windows way of menus, however I can work the OS X method. That being said, Im really noticing that on a higher resolution larger screen such as the 27, that the single menu is not necessarily more efficient. Im finding that I seem to do a lot more mouse travel to get the menus (I do try keyboard shortcuts a lot but still) . . . and I sometimes fail to ensure the window I want to menu action is the one in focus . . . leading to yet more mouse travel back and forth (and frustration). For example, having a small text editing window in the bottom right corner, and having to travel the mouse all the way to the other side of the screen just for a menu action. With that in mind, does anyone else think that if we keep pushing higher resolutions, then perhaps the menu-per-window method might be more effective for OS X ? Or maybe even some hybrid menu system which slides down the menu when a window comes in focus, and slides up when out of focus? Anyone else felt the same way?
