By default, the plugin allows to have only one sticky post at a time, which 
means that when saving a post that has been flagged as sticky, it automatically 
unsticks other posts.
Under <code>Settings</code> > <code>Lonely Sticky</code>, an option can be found that allows you to 
define how many sticky posts can exist at a time. For example, if a maximum of 
3 posts is allowed, when saving a post that has been flagged as sticky, the two 
most recent sticky posts present (if any) will be kept as sticky, along the one 
that’s being saved.
Setting the option to <code>0</code> will disable sticky posts completely.

Lonely Sticky

Works perfectly

Allow only a certain number of sticky posts at a time.

There are no settings or custom functions. Set custom post types to be sticky just as you would with regular posts, and those post id’s will be included in the result of <code>get_option( 'sticky_posts' )</code>.
PLEASE NOTE In order to integrate as seamlessly as possible, this plugin will not alter any queries or filter any functions. If your sticky posts aren’t appearing the way you want, there’s probably a good reason in your query (Is <code>ignore_sticky_posts</code> set to <code>true</code>? Is <code>post_type</code> set to a different type?). This plugin may be most appropriate for developers who just want the native sticky post UI and no other superfluous features.
If you find this plugin useful, please rate it accordingly.

Seamless Sticky Custom Post Types

Perfect

Great plugin! Hasn't been updated for over three years. But it works great, still!

Still works like a dream

Extends the native sticky post functionality to custom post types in a way that is identical to default posts.
