This looks much better! It’s much easier to keep track of your cursor and what you’re pointing at. Good job!
One thing that still bugs me is that the content on the right jumps when the div expands. This (again) makes the text change lines, which causes a really messy effect. I would change the content div’s width. Either make the nav div expand into empty space, or make sure that the content div has some space on the right to move to. Either way, the text shouldn’t jump lines (it says the same when the viewport size is much smaller, which makes it easier to read than the desktop version).
Finally, the drop shadow on your navbar is nice, but imo a bit overdone. @Gigusek already linked to the material guidelines - and I agree with his point of view. A smaller shadow would make the nav blend in more seemlessly with the rest of your page.
I think you really nailed it with the timing on the nav bar’s transitions - so keep it up!
