Custom presets for channel points.
I suggest making custom reward presets for channel points. So that you can group certain rewards into presets and use them for certain streams. This feature will be very useful for vtubers, since most often their rewards for channel points are some kind of interaction with a model, but not every model has the same type of interactions. Rewards are received instantly in such cases, and with frequent switching of models, it is not strange that some reward will remain enabled, but cannot be reproduced since such an action is simply absent on this model. The points will be debited from the account without the possibility of returning them to the user, which is not very nice for your followers. By creating presets, such incidents can be avoided because the required rewards will automatically appear in the list of available rewards.
I would also like to suggest making basic rewards that will be displayed regardless of the preset. So to speak, universal ones for which the type of stream is not important.
This feature can be useful not only for Vtubers but also for regular streamers, since everyone has very different content and everyone can use this feature for their own content creation preferences.
