Option to hide / show some elements in the popup

[WofWca]

I think it's called "progressive ". Progressively advanced idk. I think that the popup may look daunting for some users (margin (and "sounded speed"? (and other stuff?))), making it seem like an extension for nerds only, so maybe hide these inputs initially.
"sounded speed" input is less of a necessity since 1c82c22.

uBlock Origin's approach seems like the most reasonable to me right now:

This is also beneficial when the user wants to always see the chart, but they don't want the popup take too much space on the screen.

Maybe we could also implement an option for a more fine-grained control over what to show.
Also see #86, maybe it makes sense to interlink these.
