[Feature Request] Double-tap to upvote and other QOL requests

Hi there! I'm coming from Joey for Reddit and have a few QOL requests I would like to see implemented.

First, quickly double-tap any post or comment to upvote, and a slow double-tap to downvote.

Next, single tap any comment to collapse it. This should be an optional feature in settings.

Any other customizability features, such as font and colors, would also be appreciated!
