General channel has a particular role, as it can't be removed from favourites list, it can be used to spread organisation wide news. It would be great if team owner can:
* change channel name (especially translation not always show it's proper character; i.e. in polish better word than "Ogólny" will be "Komunikaty"
* allow publishing and mentioning general channel only to particular users and groups (in some cases people tend to use general to much...)
* set as administrative option if general can be unobserved- sometimes it might be crucial for organisation do have channel with high range
