Note that the example tags for rants includes Xcode... There is a reason.

In 1984 Apple introduced Macintosh and we got a computer that could barely handle multiple windows on the screen. But by 1986 multiple windows all over the place.

In 1985 Microsoft introduced Window 1.0 Yes boys and girls, no "s" because it hand only one Window. 7 years later in 1992 Microsoft got their head out of their ass and produced "MDI" or Multiple Document Interface and woohoo, had multiple windows on the screen... big boy pants 8 years after Mac.

Today we have Xcode from Apple. The old Window 1.0 engineers are apparently alive and well as Xcode is a One Window Trick Pony and if you fight with it, it starts randomly jamming your separate Windows into tabs into one window, completely fucking up your spatial organization of your working source code.

It is like the bastards going into a blind man's house and re-arranging his furniture for fun.

Xcode - it's only free if your time is worth absolutely nothing.
