What did you do?

Just browsing that page

What did you expect to see?

Two things:

1. I expected the menu on the left that lists all the types and functions to be resizable, so that long names can actually be displayed. As it stands, this is completely useless; to browse them, I have to hover over each one of them and wait for actual url to show at the bottom of the window.
2. I have a wide screen for a reason. Why are you filling the browser window with empty white space, when you could simply have expanded the individual frames to fill the whole width?

What did you see instead?

This design that makes no sense in the year 2021.
