Assegnate 2 su 5 stelle

I installed it because it claims to be able to modify shortcuts. I tried a few times to assign <ctrl>w to close the current tab but nothing changed. I did not give one star because I did not test the other features that it claims to have.

Questa recensione riguarda una versione precedente (5.08) del componente aggiuntivo.
