Add simple sorting options for redemption queue in moderator and streamer view. Particularly the ability to sort the redemption list by most recent.
Highly active redemptions can quickly stack up many pages in the history, and clicking through sets of 50 for something in the multiple hundreds or even thousands is both slow and causes browser lag. A simple drop down and "sort by most recent" would solve these problems and increase convenience.

One streamer I moderate for is chronically anxious about rejecting or completing the history, and has hundreds of thousands of entries in the queues going back years. While that isn't twitch's fault, it is certainly a problem that I can imagine isn't isolated to a single anxious streamer.
