Multi-monitor support

It would be immensely helpful if the Qt Creator tabs (Edit, Design, Help - on the left) could be split into windows that could be positioned onto other monitors. The standard is two-monitors for developers today and three are becoming easy to attain - motherboards with multiple PCI-E slots allow two video cards and ATI Radeon 5XXX support three outputs.

I find it annoying to keep the documentation into the browser or worse, run Qt Assistant, which feels slow and weird. I would be more productive if I could simply drag any tab out not another monitor, like I can with Visual Studio (for example).
