One interface tweak I'd like to see: in most clients, the repost button doesn't work like on the blue bird app, where you can toggle a retweet on and off. Rather (at least in Amethyst), if I tap it twice, I boost the original post twice. I get that it's more difficult to 'recall' the original boost, but maybe at least have a popup which says something like "You've boosted this once. Boost again?" Sure I'm not the only one double-tapping posts expecting to toggle!
