> Back button works
Maybe a little too well... I tried a whole bunch of channels to get an idea of which ones work, and my history was too full to get out of the site. Maybe every channel change doesn't need to push to your history list.
Very good point. Thank you, and I'll put a limit on it. 10?
Generally filling up the buffer is fine. It's perfectly normal that after viewing a certain number of documents one has to manually decide where to go.
You know what you need. A button that goes back but instead of going to the prior document goes to the first document with a different domain than the current one.
Tangentially, I wonder why browsers can't store more than N history items... even from the same session.
