This thing was kind of a proof of concept for something else I was doing, but it seems to work well enough to release.
Adhesive is a WordPress plugin that lets you easily mark posts as sticky. Adhesive is different than other plugins I've found with similar functionality for two reasons:
- You don't need to modify any WordPress code.
- You need only check a box when you want to make something sticky.
Other stuff that you might want to know: Adhesive uses post meta fields to store its sticky status. Sticky posts only appear in the categories that they've been assigned to. If you've modified your index.php heavily (fetching the $posts array in a different way than the default), then this plugin may not work for you. Adhesive should maintain the posts_per_page setting in your options - I'm not sure whether other sticky plugins do this.
The upside is that if if doesn't do what you want, you can just deactivate it and delete it. :)
To install Adhesive, drop the file in your plugins directory and activate it on the Plugins tab. That's it!
