Need means to reset localStorage view state

[davkal]

Aftermath of #1853

This is a bit edge casey but do you think we need some kind of localStorage recovery story? If you have a terminal open, notice some bug we've introduced which crashes the app...

refresh will reload that bad state from the url
clearing the url will now also load the app into a bad state from localStorage

@davkal how about another little icon in the bottom right that would clear localStorage's view state then reload the page without any state in the URL.

Something like this:

It could say "Clear UI State" on hover maybe.

Or, we could add a keyboard shortcut that would have the same behavior.

I would put the Clear UI state button in the help window. Of all the icons, it will be used the least often, by orders of magnitude. Maybe create a new section in the lower part of the help window?
