We revamped the upvote/tipping UI partially.
We have a new upvote button and it works the same but changes its look based on how much you've tipped (huge ups to @kr for this design). How it works:
That's pretty much it. I have another update I'll deploy in a couple days that will also alter the UX slightly and give the user some instruction around how tipping works.
Other updates: top and recent are now their own buttons in the navbar (thanks to both @kr and @nout for suggesting this), small adjustment to spacing of posts in the feed, the price no longer displays cents, and if you don't want to view the price you can tap the price to eventually get 1sat=1sat.
