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.

이 검토는 현재 부가 기능의 이전 (0.10.4) 버전에 대한 것입니다. 

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