Does Terminator support undocking a terminal session?

This is not currently possible. You are welcome to create a bug report using the link on the right hand side of this web page, but I think it's unlikely that we'll add support for multiple windows (at least any time soon!)

May I ask why? It should be not that hard to implement this using `screen`. You would simply use the command `screen` as the binary to run on `fork_command()` for every terminator session (better: `screen -S <session_name>`). Then, when the user wishes to undock the session, terminator would detach the running session (`screen -d`), then create a new window with the vte widget in it using `screen -r <session_name>` as the binary to run et voila: The user sees the old session in a new window that is independent from the "parent" terminator window. If there is a real interest in that feature, I would try to implement this on my own and send you the patch. (Maybe I will do that anyway and create a bug report with the patch attached in the next days... ;P )

That seems like a mildly hacky solution to me, and is something you could do yourself by just running screen and opening a new terminal window.

Multiple windows is a contentious issue because of the way the terminal widget works - its performance is very poor when all instances of it are part of a single process, so this is something we have been keen to avoid where possible.
