Will this load sidebar faster ?
Or you just want to disable the unuseful widget for users ?
@Mael: no, its not for the performance, is for a customzing in backend for custom. Maybe you write a theme with widgtets, and the custom will only your new widgets for his users in backen - you must deaktive the default widgets.
Does anyone know how can I unregister the Menu Nav Widget?
This worked amazingly well, thanks.
The one thing I'm still desperately looking for and can't seem to figure out is how to, within multisite, have some widgets already activated on the sidebars by default for every user activating this theme.
I would like to have them activated on the sidebars by default without hardcoding them in the theme, because I would like my users to drag them out if they prefer, or move them around on different sidebars.
It's slightly off topic but I would really appreciate it if someone knew how to do this. I did find someone asking the same thing on the wordpress forums but nobody knew the answer over there.
