This plugin helps you create a series of posts. It creates a new taxonomy named ‘series’ (can be modified via filter, see FAQ). There is no setting needed for this plugin. Once it is installed, assign posts you want to group as a series via post editor.
The plugin also creates a posts navigation on posts that belong to a certain series. See screenshots for the examples.

Easy Post Series

Works beautifully and doesn't have a sucking frontend design, as other similar plugins do!

Very good!

Organize WordPress Drafts with “Draft Types.” Think of draft types as folders for sorting your drafts. Use the default types or add your own custom draft types.
Features:
<ul>
<li>Assign “Draft Types” to your drafts to improve your editing workflow and de-clutter your drafts.</li>
<li>Create your own Draft Types. Default types are: Idea, Outline, Rough Draft, In Review, Needs Images, Ready to Publish.</li>
<li>Sort your draft posts by draft types. When viewing your drafts, you will see a draft types column that can be sorted alphabetically.</li>
<li>By default, works with posts and pages. See the FAQ for how to configure this to work with custom post types.</li>
</ul>
Have an idea to improve this plugin? I’d like to hear about it.
