It’d be great to see a red dot indicator in “Guide” view (and even “On Now” that shows whether a program is scheduled for recording / being recorded.
Guide View already has indicators:
Red. - Being recorded now
Orange - Scheduled to record
Green. - Recorded already
Hmm, that’s odd. The indicator isn’t showing for me…
On Web UI currently, assume devs are still working feverishly on ATV presentation for the Public launch.
Ahh, got it. Guess I should’ve clarified that I meant the ATV interface. =)
Quick response to your request for ATV Guide indicators. Working now except Green (Already Recorded), which @tmm1 will be adding soon. 
I’m finding that the “scheduled to record” color indicator in the guide is showing for all shows with multiple listings even though I have only one scheduled to record. Is this a bug?
Yes that is a known bug. It is purely a display issue and the DVR engine will still work as expected.
