Artemis might use a swipe gesture to visually hint at the relation between upvoting and boosting, as shown in the main animation. Here’s a static app mockup with both swipe levels displayed. I’d also imagine that there should be a setting that auto-upvotes posts when boosting.
Such a clean design of the whole thing, OP you should be helping out in the UI
Well, I’m in the Artemis discord channel and plan to pitch in several ideas/mockups here and there, so there’s that. Not sure whether I’m needed at kbin though)
