Assegnate 4 su 5 stelle

First of all great addon. Add lots of functionality which is awesome. But I really need this one here: superuser.com/questions/21088/mozilla-sunbird-multi-day-event-looks-weird-in-calendar If this would be possible to add, I will give the full 5 stars. That would be amazing :)

Questa recensione riguarda una versione precedente (6.2) del componente aggiuntivo. 

Unfortunately, this feature is beyond the scope of the Calendar Tweaks add-on. This feature really needs to be added into the Lightning calendar add-on. The original feature request that you refer to was made in 2003, so the change is probably not easy to make.
