[Update] Add a Tagline to your Google+ Collection

A much-requested feature for Google+ Collections is rolling out today - The ability to add a brief description to your collections.

Sometimes a title and cover photo isn't enough to express what your collection will offer, which is why I'm very happy about this update to Google+ Collections. Adding a tagline to a collection is optional, but most will probably want to take advantage of the new feature as it may help sway the minds of potential followers.

As for length of the tagline, there's enough space for you to add a brief sentence, so be sure to keep it short and snappy (80 characters is the limit).
Collections taglines are displayed underneath the basic info and separator
To add one, just go to Settings > Edit collection and when you've typed your tagline, hit the blue Save collection button and you're all set. Easy peasy.
Look for the cogwheel icon on the right of your collection header
The setting is currently only available for web at the moment of posting, but I expect a Google+ app update to roll out shortly to fix that.

What do you think of this small but big Collections update?
