Right down at the bottom left corner of the page is a dropdown menu where you can change the site's style. There is a mobile option available that you might want to try. Personally when I'm on my phone, I just use the full site too, but you never know - maybe you'll like the mobile style better? Worth a try at least. If you try it and don't like it, there's a "return to full site" option (or something similar) that will get you back to the default.

Also, just so everyone knows, work is ongoing behind the scenes to address things such as site performance and appearance, etc. I don't pretend to understand it, but those who do are on it.
