I really like the idea of a built in menu to offer bit redeems rather than having a menu posted via commands etc. We can use the same API access and interface as the channel point interface, and allow disabling certain power-ups. Also, with this, it would probably be best to have the menu be two buttons so it doesn't get too bloated.

This would absolutely increase the income from bits, as people would be able to see exactly what they can get for their bits rather than having to find that information elsewhere. This is good for both viewers, streamers, and twitch itself.
