I’ve just released version 1.3 of BP Labs; it’s a plugin which contains unofficial and experimental BuddyPress features for testing and feedback. Long overdue, the update fixes a problem with autosuggest, and introduces a new feature: Like Button.
Like Button requires the Activity component, and simply adds a “Like” button onto WordPress’ Toolbar when viewing a blog post (or any other post types). Likes are grouped together and shown in the Activity stream. It’s pretty simple, but fun. Let me know what you think of it.
