Works nice, please make a small improvement, make the menu item always have the URLs in it even if it's only 1 URL because otherwise it stretches the menu like on the left

Edit:
Fixed in version 1.3.0

Edit2
Probably needs some work but making the urls available in a separate page would be a good idea to make the addon work on Android.
