Remembering to post every day, and which days you already posted, is super easy with this plugin. 
It shows you a calendar with days red when there isn’t a post, and days green when there is. Green 
days you can hover over and see the title of the post, and click to edit the post for that day.

A simple calendar that displays when you edit posts, showing which days you have posted on.

SOUP creates a widget in your sidebar which allows you to display your upcoming posts (scheduled, drafts, or both) to your readers. The idea is to entice your readers to come back and read the article once it gets published, or better yet, subscribe to your RSS feed and/or newsletter.
Here are the configurable options for the widget:
<ul>
<li>Title of sidebar widget</li>
<li>Number of upcoming posts to display (always in ascending order – newest first)</li>
<li>Choose whether to show date of upcoming post</li>
<li>Display order of the posts (next post first or random order)</li>
<li>Message to display for when there are no scheduled posts or drafts</li>
<li>Show/hide newsletter link</li>
<li>Include link to sign up to newsletter</li>
</ul>
I’ve got plans to continue developing and updating this plugin.
