When navigating the menus, the browser back button doesn't seem to work, and nor is the way to go out of a particular menu obvious. I ended up just refreshing the page to get out of stuff.
Same here - feels very unintuitive to have to click the name of the page you're currently on to go back to the parent - feels like it should display 'Parent > Current' rather than just 'Current'. And probably respect browser back behaviour if possible.
Remember back in the 90s with full Macromedia Flash websites and trying to link to specific sections of a site?
