I absolutely adore the positioning of the table of contents. The design looks clean, utilitarian, and overall well executed.
That being said - and this is more a critique of modern design - I absolutely hate the suffocating roundness of the element corners. It's an aesthetic that drips with overfamiliarity and a patronizing attitude. It's the visual equivalent of being put in a padded room, or having a distant relative who you have nothing in common with and have not seen in years trying to relate to you with anecdotes about your childhood that you can scarcely remember.
