@petra.pik Any further on this? I'd also like a "jump to live" button. Less desirable, but also workable, would be having the playback controls have a "stop at end" option; then I could drag 10 minutes into the past, hit play, and know that the playhead has stopped at the "live"/"latest" position.
In case it helps you to know why I care: in the afternoons leading up to outdoor sports, living near mountains, I watch the weather radar obsessively throughout the afternoon trying to predict when it might be safe to go out, how likely it will be that we need to call off games. I occasionally drag the playhead into the future to gauge the speed of the storms, and then need to futz around to try and get it back to "live" mode.
