1. I’m not sure if that’s possible, as WP doesn’t categorize posts by their sticky status. You could tag those posts as something like “featured”, which you could then target in that featured post area.
2. You should already be able to show the date. Check the “Meta” section.
3. No set date yet – a lot of the plugin has been rewritten to allow for better expansion later, which it why it’s been taking a while.
