The "media" stream on YT showed the on-board cameras continuously until a few minutes ago (https://www.youtube.com/watch?v=nA9UZF-SZoQ) Not sure why the main NASA stream only cut to them briefly
While they did have a time-graph line, it wasn't relatively spaced just integer ticks along the line.
No list of upcoming steps (1-3 next events) with associated -T+ timestamps they should happen at.
Most glaringly, while they did have a T clock up at some points, there was not a single, always in the same spot, T-clock, and they had a like 90 min hold at T-00:10:00 which is absolutely useless for viewers. It was tough peeking in every so often to tell what they were even waiting for with so many 'ad's / filler segments of videos that should be on the website / youtube in a press kit.
I agree I want to see a scaled timeline with upcoming milestones. I'd like to see basic telemetry (speed, alt, attitude) and a T count at all times, (with an estimated launch time (L-time) before launch). I actually like the way ISRO and ESA present time vs altitude and time vs velocity graphs with an expected line and an actual telemetry line. So I'd welcome something like that.
We got video from some engineering cameras later on in the launch, but the more the merrier; views of Earth from the rocket can be spectacular. Of course there's a practical matter of support for them and TDRS downlink bandwidth, but I think the outreach value of them should be a consideration for NASA.
The truth is, NASA’s strategic goals go beyond delivering payloads. E.g., they also have the explicit goal to
“Inspire and Engage the Public in Aeronautics, Space, and Science”
