It takes time to save a post or page that you’re working on to check out the dates that you may have scheduled other posts. Even in WordPress 3.1 the only place to see the dates of scheduled posts is on the Posts page. When you’re working on pages or posts, it would be nice to see at a glance when other content will be posted to the web site.
I reviewed two plugins that were developed to display the scheduled posts as a Dashboard Widget.
Future Dashboard Widget creates a widget for the dashboard that lists the Scheduled Posts by date, including the post titles and first line of content. The entries are listed in reverse time order so the next post to be posted will be at the bottom of the list. A link is provided to see “All Scheduled Posts”.

Note the day, date, time, title and text format with last posting listed first.
Dashboard: Scheduled Posts creates a Scheduled Post widget for the dashboard, but lists the entries in order so that the next post to be published will be listed at the top of the list. A link is provided to see “View All” scheduled posts.

Note the title, date and text format with first posting listed first.
I’m going to go with the Dashboard: Scheduled Posts plugin. I like the widget format better than that of the Future Dashboard Widget plugin and the order that the posts are listed seems more intuitive. Thanks Viper007!
I forgot to say that one reason I like the Dashboard: Scheduled Posts plugin is that the posts are listed in the widget using the same format as the provided Recent Drafts dashboard widget. This makes is super easy to see everything at a glance.
