The Hub - A way to enable/disable links

1. I would like to have an option to disable/enable link to the hub. I can always enable them on live site which is what we actually want on the hub so we can monitor, update, backup etc.
2. For a local development or even staging site, it really might be better not to have them so having that option would be awesome too :smiley:
3. Not to mention if u have 20 sites, that would be at least 40 sites display on WPMUDEV hub, with staging it goes to 60 without any sort of tags or categories management it gets awfully tedious to manage.
