Thanks for the review, Justin

I also like the simplicity of the Plugin and I'm sure it's getting additional features over time. Your proposal to add some form of taxonomy (label, tags, status) and make it possible to show the label besides the title and the description as separate column independently would be great. But then it's getting more of a checklist then a description and there are already plugins out there that do an excellent job of this, eg. Pre-Publish Checklist by Brainstorm Force or PublishPress Checklists. Both of them allow their use on other post types. But if other post types will show the "description" is another story. In my tests with Sugar Calendar (Lite) and Seriously Simple Podcasting they didn't show up. It's likely that would work in some simple post types (it surely does for pages).

Looking forward to updates.
Besides the "labeling system" with tags I'd like to see an option to add checklists directly in the description. That would be more flexible than a fixed checklist per post type as it's done with other checklist plugins.
