It is way to early to tell how this era is going to shake out. They're all likeable in their own way, but so far, we just haven't seen enough of them to get a baseline, let alone compare them to previous TARDIS teams. That being said, I think Yaz had [i]by far[/i] the best introduction of the three in TWWFTE, and has exceptional potential, but she's been underused so far.
Just chiming in to say that yeah, the biggest issue I see at this point is with the tables, and then, some of the sidebars. I know the coding for those is so redonkulously dense. For the moment, changing skins makes it legible, though. The time and extensive work required to pull this off is much appreciated.
