Consider base-64-ifying state

[emi2k01]

Because the state is stored in the URL, it has some problems when it's shared even though it's URI encoded. I don't think being able to change the state directly from the browser's URL bar outweighs having a URL that you can just copy paste without being afraid it might interfere with the platform's formatting.

An example of a problem is that URLs can have parenthesis in them and if you try to paste them in a non-commonmark compliant editor (like Reddit's), the URL will conflict with markdown's link syntax. In commonmark compliant editors you can wrap the URL in <>.
