I'm a long-time user of Embarcadero C++Builder peeking into Qt Creator (Ver. 4.4.0) at the moment, which seems to be well-suited for all kind of C++ development tasks and thus might be pretty productive.
Unfortunately there's one major drawback slowing me down significantly in comparision to C++Builder: I can't find any setting enabling the re-arrangement of Qt Creator's default IDE layout, since it's just not mine.
Is it really the case, that such a classy-looking IDE won't have that kind of feature nearly every other major competitor has?
Maybe there's an undock setting I'm not aware of?
Short answer: It is not possible to undock any panel or view in QtCreator 4.4.0. But some sort of re-arrangement of views is possible.
There are left and right panels enabling some customization:
Unfortunately, that's about all the customization of layout there is.
