[Qt-creator] support for multiple top-level windows?

[Joel Nordell]

Hello all,

What you think about adding support for multiple top-level windows to  
Qt Creator?  I use two displays on my workstation, and having just a  
single monolithic window is too limiting to me.  (It doesn't allow me  
to make use of both monitors.)  I've briefly looked into what it would  
take to modify Qt Creator to support an "Open in Separate Window" menu  
action, and here is a VERY rough patch to illustrate the idea.  The  
patch needs a lot of work, and is nowhere near usable at this point,  
but hopefully it is enough to give an idea of what I'm thinking.

Does anyone else have any thoughts/opinions on this?
