Is it intended that you can only listen to the topic for your own channel? I would have hoped to also see redemptions in other channels, since currently it’s only possible to see custom rewards that have a message attached through IRC. They also only have a custom-reward-id=<id> attached, with no way (that I know of) to translate that into the reward name.
So it would be great if it would be possible to either listen to other channels as well (although that may not fit your intended access model) or at least a way to translate custom reward ids into a reward name.
