Ability to swipe pin to pin

It would be handy to be able to swipe through the screens, pin to pin. This might be resolved by #47 with a single column option.

Aye, looks like this duplicates #64 too. Though that wasn't titled well.

This feature could build on #47 and #64 but won't be implemented until after those exist.
