Session Storage capability

Love this, actually so much nicer than having to work with Ports to get my stuff saved!

Is there some plan in the future to extend this functionality to look either at sessionStorage or localStorage?

The API between the two is fundamentally the exact same - would just be nice to be able to open a new tab, and have a "clean slate". It's really helpful for when you want to, "refresh" the tab and land exactly where you were.

Thanks for the issue! Make sure it satisfies this checklist. My human colleagues will appreciate it!

Here is what to expect next, and if anyone wants to comment, keep these things in mind.
