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.
I love the way this looks! Tiff for Squabbles does something similar with their menus, and I’m really digging it so far. Would love to see that in Artemis, too!
Since you can upvote and boost on Lemmy, I think it’d be a good idea to have 3 levels to the animation.
