Make local user settings

[amoutonbrady]

I'm among those people that prefer larger coding fonts but that would feel selfish to impose that to every user as I feel like this is not so common.

What I'd like to see is a gear icon somewhere that would introduce a setting page that would be store locally (either via localstorage or indexdb with idb-keyval for example).

I'm sure this feature could also introduce a lot more personalisation without going full crazy and produce a poor man version of codesandbox.

Here are a couple of things that I have in mind as I write this:

• font size
• coding font
• dark/light mode (already exists, just need to move the location)
• minimap or not (easily switchable today)
• default vue (code or output), I know some people like Ryan tends to look a lot at the output tab rather than the iframe.
