A just-nice-to-have would be to have the currently-reading and currently-watching widgets always visible, even if they are empty (or to be able to configure which widgets are visible in account settings). It’s small, but being able to always access “My books” from the dashboard widget would be one less click through a menu if I’m starting something new while my currently-reading is empty, instead of having that widget disappear when I finish a book.
We tried this but too many people complained about it 
Also it does take a lot of the screen space, so we also felt it was a bit too big.
In the future we are thinking of maybe having a more configurable dashboard, so we could address things like these with it as well then. Closing this thread for the time being.
