This plugin displays a configurable list of reminders on the post administration screen.
Lorelle, of Lorelle on WordPress, requested a simple reminder plugin that could be used from the administration panel within WordPress. I decided to deliver with this little piece of code.
Your reminders are input through the WordPress administration interface, and you can format them in a variety of ways. You can change the text color, background color, and make the text strong, emphasized, and underlined. Reminders are stored as posts in the database.
When displaying the reminders, each reminder has a checkbox that you can check to mark that you've completed that item. The item will be dimmed when the checkbox is checked and undimmed when unchecked. Use this feature to make sure that you've completed everything that you should have. Checked reminders will stay checked after saving a post.
