I am looking for a way for my users to mark topics as permanently read. The marked topics should not appear in the search-results like normal search, "New posts", "Unread posts" and so on.
Maybe with a checkbox/button in the search-results to toggle this on and off? With on as default.
Or a button that disables the hiding just for one look, and then activates the function on next page reload again.
Is this do-able, also for large forums?
