Wrong. If it doesn't work, it's a bug.
So the remotegui's missing graphs and missing client display in the transfer window are bugs too ?
I define "bug" as "supposed to work, but doesn't" and "missing feature" as "simply not implemented".

Stu: Is this something which is addressed by lfroen's work on EC?
I don't think so.
True multi client capability adds a whole new dimension to EC complexity. Open a file detail dialog in one gui, the remove the download in the other one and see what happens - there are dozens of examples where the behaviour is simply undefined now.
