I’m one of the folks that doesn’t at all mind the WordPress Admin Bar, added to WordPress in version 3.1. Using it as much as I do, though, it bugs me just how sensitive the Admin Bar dropdowns are. I was in the process of fixing it for myself, when I figured it would make a nice simple plugin that others might benefit from as well.
This plugin slows down the dropdown so that it only opens up after a moment’s hesitation on the Admin Bar. It only effects logged in users, so shouldn’t add any overhead to your site.
You can download the Admin Bar Hover Intent plugin from the WordPress Plugin Directory.
That’s pretty much it, since this plugin is pretty straightforward. Hope you find it useful!
