Kodi updated to v17, I don’t even know where to start

Kodi updated to v17 and now everything is completely different. It looks absolutely nothing like it used to and I am so upset that I don’t even know where to start. Is there any way to go back to what I had before? If I go to Settings->Advanced->Backup and restore skin settings that does nothing.

There are so many missing options on the Home screen menu. How do I make the text all caps again? How do I make the menu wide to span the whole screen? Why do the widgets look like garbage now? How can I display submenus all the time instead of having to press down?
