Superb plugin

For each post:
I use the readability checker religiously (but it’s *really* hard to get a good rating)
I then use the SEO checklist as a… checklist. It’s excellent.

It would also be nice to add these features:
1. Best publish date/time per post
2. Ensure tags have been set
3. Ensure categories have been set
4. Other custom rules (e.g. I like to have a short snippet after second paragraph)

For a free plugin, this is excellent. Thank you.
