[Qt-creator] Why QtC does not use QDockWidget for most tool-panel

[Prav]

Hi, Ziller.

Could you please comment this idea (may be it can make previously discussed problems with dockability easier):
> There is also a way to not touch sidebar but create new dockable pannels with same content as in pannels of sidebar.
> I am not sure that I described idea clearly ... can do more if needed ...
> but this seems like the most easy way to adapt dockability ... like do not touch current structure but add dockable panels which will
> reuse implementation of current side-bar pannels (which may be need to be adapted a little bit for use in both sidebar and in dockable pannels).
