slideout navigation (mobile and desktop)

Hi there, wanting to do a few menu things:

slideout menu the same for desktop and mobile, burger top right, full width and height of page, centered menu items, x to close visible top right.

I've tried a few of the options I've found on the forum but nothing that works completely - seen that this will be available in the update soon, is it worth waiting or is there css that's not too complicated for this?

Thanks :)
