Wurdearring: 4 fan de 5 stjerren

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.

Dizze beoardieling giet oer in eardere ferzje fan de add-on (0.10.4). 

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