For many, Pinterest is the go-to tool to plan out ideas for parties, weddings, and other events. Now, Pinterest is trying to make its platform even more useful for group planning.

In an update today, Pinterest is adding an activity feed for group boards, which acts as a timeline of recent activity like pinned items, likes, and comments. That should be helpful; before, no one was notified when a new comment was added. But the most useful addition may be the added ability to simply leave a comment without attaching it to a specific pin.

Now, group members can just leave a message in the activity feed to start a chat thread, which others can respond to. That should make Pinterest’s group boards more useful for starting and hosting discussions, rather than just generating ideas.

The features launch today on all of Pinterest’s platforms, including mobile apps and the web.

Pinterest has been changing how people see pins and boards this year, with the introduction of a number of new sorting options and, in March, the launch of a nearly algorithm-free board that just shows your friends’ stuff.
