I have many many apps running in the background some are infact two or three windows of same program, i.e. Firefox 3-4 windows and Xcode 3-4 windows etc...
I know that I can switch using ⌘+⇥ but that only switches on programs and I want to go to each individual window.
I've tried spotlight and it's not what im looking for. Also, I do not prefer to install any paid software and would like to use build in features if possible.
