I heard that votes have been changed to behave closer to how people would expect, and boost is staying here as well. So I had an idea how to bring it all together in the interface.
Sidenote: you don't have to click the links here, the images are also posted inline in the comments below.
An app (either Artemis or an official one) might use a swipe gesture to visually hint at the relation between upvoting and boosting, as shown in the attached 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.
And on the web, it's probably a good idea to consolidate all the voting buttons into a single block by adding an additional button at the top.
Edit: I’m disappointed in you guys. How come no one noticed the memes? :)
Love the animation so much, I'd be tempted to boost everything just to see it again. Completely nitpicking here but maybe a version with the boost-arrow centered might look even more clean? I get the idea of having the arrow "evolve" but maybe can save that effect by having it "evolve" and slide to the right at the same time
Idk, both ways are used in iOS apps, but centering is usually done when opening a slider with several actions. Centering just one icon adds unnecessary movement in my opinion. The way I've done it makes your eye easily lock on an icon, since it doesn't move about once revealed. Remember, you're sliding this with your finger, so it's not going to be fixed in one or two places, but it'll move to recenter itself with every tiny movement.
You're completely right, it's multi-action sliders that I'm thinking off!
Thanks for going over your reasoning, seems well thought out and I can see my self "chasing" the boost arrow with my finger if done in the way I've described so point taken :)
