Awesome, thank you for giving it a try!

These are all good features to have.

1) About page and custom pages are on the to do list. I need to work out a simple way to add this content from the user's perspective.

2 & 3) Great idea for the blurb and custom site title.

4) Interesting, hadn't anticipated this request. Would you like a global option to hide publish dates?

And yeah, IA writer is excellent. It's great to be able to publish a blog post from inside their mobile app!
