Add a way to see how many bits you've used in a channel
Perhaps /bits or /bitcount. Might contribute to the idea of working towards the next badge tier for a favorite streamer
If you click the Bits icon, or start typing "cheer#" it comes up with "You have X available bits, you have X bits until the next badge." Unless you're over 100,000 bits cheered, it's a matter of simple math to determine how many you've cheered.
