[Qt-creator] Multi-Tab editing and AutoHide

[Ilyes Gouta]

Hi there,

Multi Tab editing is now the de-facto standard way for developers to
edit their code on numerous IDEs, and it would be really nice to have
it in QtCreator too.

AutoHide, is for the lower build (compiler messages) window to
"auto-hide" as soon as the developer's mouse cursor leaves the said
window as soon as the compilation finishes. We can implement this
feature too for the project's files explorer, the goal being to offer
the most of the screen area to the source code editing window.

Any chance to get these into the next releases of QtCreator?

Best regards,
Ilyes Gouta.
