Thank you, this works with the new facebook theme that broke the old ones.

Glad that it helped you. I know there may be some bugs hidden somewhere and the performance doesn't seem like very good. I'll improve it on the way :D

yes, i notice that but its good enough. ill keep an eye on this repo to see all your updates :)
