Allow streamers to customize the background of the reward buttons, not just the icon, and make the icon optional. Right now the reward redemption buttons look very plain and too similar to one-another because they're just solid-colored shapes with tons of blank space. I would love to use an image to cover the entire body of the reward button, not just a small icon in the center. Not only would this allow the rewards to be more visually distinct from one-another, but it could be used to make cool visuals by combining the background and icon (i.e., a reward called "Choose what OW hero I play" could have an Overwatch icon with a blurred screenshot of Hanamura as the background).

The 'Get Custom Reward Redemptions' Endpoint requires the call to provide a reward ID and a redemptions id/status. This means in order to get a list of the last 50 channel point redemptions for a channel, you have to do a separate request for every single reward available on a channel.
This seems way over complicated to just get the last redemptions on a channel.
Ideally, you could call this endpoint and get the last 50 redemptions that include redemptions of any of the rewards. Then a parameter of offset could be provided to get more redemptions.
Not sure why this wasn't the way it was made initially, but this would make it much easier to use.

The set up would be an affiliate/partner would be able to create a collectible series of emotes/cards etc that their viewers could then spend loyalty points on purchasing packs that have a random selection of the collectibles inside.

Once a viewer has completed the series, they are able to prestige the collection and advance the grade by collecting the same emotes/cards again but more of them in order to progress to a grade that is a higher collection and each collection completed could earn the viewer a badge.

The idea behind this is to increase the incentive of a viewer's stay by earning more points to collect more and to earn better badges

People are suggesting an API for channel points, and initially it seems like a good idea, but a forum post I saw elsewhere explained the privacy concerns of being able to track channel points through an API. But instead of an API for channel points, what if we were able to link REDEMPTION of channel points rewards to an API, and additionally create native Twitch commands that configure channel points acquisition rates and conditions (ie. active chatters vs lurkers or 10 points/5 minutes default vs 20 points/5 minutes default), as well as give streamers the ability to add or remove points similarly to their ability to do so with bots (and these same commands can be used automatically by local chat bots with the necessary permissions run by the streamer)?

The reason I'm suggesting this is that giving streamers, or anyone else, the power to monitor channel points thus gives them the power to track the behavior of any user they choose, especially if they can monitor points in every channel that user watches. That is a MASSIVE breach in privacy! But with an API that basically alerts a bot every time a channel points reward is redeemed, what the redeemed reward was, and who redeemed it, channel points can become a more effective replacement for the localized points systems included with chat bots. These points would still be housed on Twitch and the amounts kept private from other users, but we would now become able to coordinate channel points rewards with a chat bot's response if we wanted to.

The channel points settings, on the other hand, would operate as they would with any chat bot, except they'd be native to Twitch instead of the localized chat bot. This would also not include an ability to query channel points, in case you were wondering, because there's no need for anyone other than the user who's accumulating those points to know how many points they have (which they can see at the bottom of chat). If they decide to share their total channel points, they can say it in chat, themself.
