Sweet—very much prefer the thumbnail images, excellent to have both as options!

We just pushed a few small updates to beta:

• You can now reblog any post as a Text post, Link, or Quote.
• If you prefer browsing Photo thumbnails in your Dashboard (or just need to be discreet at work), you can uncheck “Show full size photos” on your Preferences screen.
• Based on this clever Dashboard hack, nested blockquotes now get darker, making them easier to differentiate.
