Experimental Chromium features
Polypane is a browser for developers, so it comes with some experimental Chromium features turned on by default. This means you can use Polypane to try out upcoming features before they make their way into regular browsers!
Prefers reduced data is a new media query that lets visitors signal they want to preserve data. You can emulate it in Polypane by going to the emulation section above a pane and toggling "prefers-reduced-data" to "reduce".
We wrote an article about what you can do with prefers-reduced-data, read that here: Creating websites with prefers-reduced-data.
<selectmenu> element is an experiment to provide a more customizable
select element, with a stylable interface and options.
