Being able to see the list of dependencies on a card is great, but in almost every case the card title is truncated so much that I can't read it without hovering over with my cursor, which is quite frustrating.

(This will become even more of a problem if/when you add a tab for children cards.)

FWIW, personally I don't really need the Board or Collection fields there, so for my use case just getting rid of those and giving more width for the Card field would likely solve the problem.
