G+ Hide Posts is a Chrome extension developed by Ralf Haring. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. This free extension allows users to hide posts on Google+ without permanently muting them, ensuring they still appear in future search results.

Google+ provides a method to mute posts, but this results in a permanent block. Muted posts will not appear in future search results, and unless users save the direct link, they cannot unmute them. G+ Hide Posts solves this problem by offering a way to temporarily hide posts from the user's stream for one week.

With G+ Hide Posts, users can keep their Google+ stream filled with only the most interesting and current posts. All other posts will still appear in searches, ensuring that users do not miss out on any relevant content. This extension provides a simple and effective solution for managing the visibility of posts on Google+ without resorting to permanent muting.
