Please send this to the Peertube developer. Consider also that until recently it's likely that having videos load fast on peer2peer and adding features like streaming likely had a higher priority than interface polishing.

But you might be asking for something impossible : the focus is on the different servers, and having a "suggested videos" page is seen as an anti-feature because it involves making an "algorithm", at which point you are editorializing, become (legally !) responsible for what you select, and are close to become a platform yourself, something that you started out by fighting in the first place !
