Let's say I have been working in a given Vim session for some time, and come to a point where I *really* would like to have everything I am looking at in **GVim** instead.

The actual use-case is a terminal Vim session with a large number of windows... I'd like to click-activate them instead of going through Ctrl-W each time, something that can be done in GVim but not Vim (not mine, at least).

Is there a way to take the buffers / windows / tabs currently open in Vim, and open them in GVim instead?
