schulzha this is a good feature request. Thanks.

While, this definitely is a minor feature request I would like to case about a 60 votes on behalf of me and teams.  We have had team members who have gone back to the legacy ui just because when you open blue ocean you have a wall of favorited stuff you don't care about and it takes dozens and dozens of clicks to remove them. 

Allow us to opt out or un favorite all or something. 

I also am having this issue, and while this isn't a good long term solution, the following brought my blue ocean load times from 20s to less than a second. Go to your main dashboard where it shows your favorites and run the following JS in your browser's console:

arr = $$('div[title="Remove Favourite"]')
for (var i = 0, len = arr.length; i < len; i++) {
arr[i].click()
}

Then refresh and enter it again! Note that I had to do this ~15 times before I got through my backlog of favorites, as it was displaying a max of 100 favorites per refresh.

Here is a script for the script console to remove all favorites:

def user = User.get("<your user id>")
user.getProperty(hudson.plugins.favorite.user.FavoriteUserProperty.class).data.clear()
user.save()

so jamesdumay can they just remove autofav plugin - or will that upset the apple cart? 

This seems like a great feature request (another option if paginate the fav data - but I don't think we have the means to do that now), so disabling autofav would make sense (can be a setting of the autofav plugin?)
