To your points.

I've intentionally left out the delete function, nothing lasts longer than a week without manual intervention. Despite using the service daily, I can't think of any cases outside of me manually messing with data as tests that I've missed having a delete.

This is a great idea, and I'll definitely be making a new initial login "landing" page!

There's something odd in my Apache setup, as the slowness looks like it's from load, but there's not that much strain on the box. The other issue, which I've tried to optimize as much as possible, is that it loads a LOT of JS when you click the bookmarklet, and it doesn't show the message until it's all done. I need really should pare that down some more, thanks for the push!
