Feature request - drag file from and to tab bar

Question

Hello - I've just discovered Office Tab and I must say I think it's marvellous. I really missed the ability to have several documents open in a single window that was there in the 'old' Office (pre-ribbon) and this is even better - no cluttering up the taskbar and really easy to see which doc is which.

One thing - maybe two - that I'd like to see added in a future release is the ability to drag a file from a tabbed group and open it in a separate window, also to drag a doc that is open in a separate window to a tabbed group. Or maybe (also) have two or more documents open side by side within the same window?

Anyway, thanks for the productivity aid. I'm trying to get my work to pay for my licence but if they won't then I'll buy it myself. Excellent stuff.
