Really nice app, could use a couple additional features

A thoughtful and elegant way to browse reddit on the go. Now my preferred default client.

A couple feature requests:

1. Allow viewing of videos in landscape
2. A toggle to allow sound from video or music links even if the iPhone mute button is on
3. Submissions linking to other reddit posts (eg /r/bestof) should be readable natively instead of via the built in browser
4. Double-tapping to zoom on an image
5. Ability to change text size
6. A toggle to collapse all comments within a given thread, rather than just the children of the comment you hid
