Idea: Allow regulars (or anyone) to pin their favorite rewards to be visible in a specific panel and clicking them would instantly redeem the rewards without asking for confirmation.

Motivation: Some rewards are time sensitive and made for repeated use, it would be great to enable a more stream-lined experience for using these.

Some examples from my own stream:
1. Take a screenshot
2. Channel trophy (name on screen)
3. Sound effects

How: The info box for a reward has a lot of empty space, add a "Pin: [ ]" checkbox or similar in the same space to pin it to the instant redeem panel.

This could be limited to only a few rewards, 3-5, to not be too obtrusive. Additionally it could be restricted to only specific rewards through a setting or only rewards below a certain point price.

Note: Personally I want this for viewers of my own stream as well as for other people's streams, any place where I have a few favorite rewards I always use. I think this could be a pretty good quality of life improvement for regulars of a stream.
