It is great, but does not work well with Nostalgy++ extension. I cannot write into the floating panel (nothing happens), but Nostalgy grabs the keystrokes. If I change it to "Popup window", it works well, but this popup always pops up in the center of the screen and positioning does not work.

You can bump Nostalgy++ author to apply a fix:
