The new Blogger editor has some nifty add-ons that I only just noticed recently. The first is the ability to add captions to pictures. When you click on a picture, it allows you to resize the picture, change how it is justified and add a caption. That's the red box at the top.
I noticed today a "location" button as well - it allows you to map the location of the post. I think it only works for the entire post, not for individual photos (which is a pain, since I take photos all along my rides). Still, it's getting better all the time (or should that be, "more intrusive"?)
