Hello guys I've been forced to use a Mac for about an year now and I'm still having problems to work with it. The first one is about a really annoying huge amount of clicks to get focus between windows, this is so stupid and I really cannot get used to it. Is there any way to change this behavior ? I mean ... I've focus on window A and I want to press a button on window B; If i press on button I expect to have button clicked, instead I've the window B focused and nothing more happens. That's so stupid. Pleas tell me I can change it!!! Second problem: many applications I code with have some kind of windows I need to stay on screen when I change focus. But sometimes happens those kind of windows disappear as soon as the main application loose focus. I don't know the name of those windows but they have a small and only 1 circle on the top left. This stupid bug is more annoying then the first one. To a programmer is a pain in the a**. Please tell me how to fix it. Third one (but unfortunately not last): is there any short cut to change windows between same application ? On any Linux os for example if u have a text editor with multiple files open u can switch between files with the good old ALT+TAB. Here we have CMD+TAB but it's working only with apps. I know there is the F10 key but that involve an annoying animation and the use of mouse; unthinkable!!! Many thanks for help. Please help me to (at least) like OSX. So far it's only a pain in the back to work with.
