Uh oh, the one currently in third place -- making it easy to change settings for multiple goals at once -- I kinda don't want to win. (Good thing @bee stopped me from committing to fix whatever the winner was!) For one thing, it's not very newbee-impactful, which still needs to be our priority right now. And also I kind of philosophically disagree with the use case. When you go on vacation, for example, that means some goals should be flattened but maybe your steps goal should be steepened. Other goals have plenty of safety buffer and it's a shame to mess up a nice steady slope if you don't need to. So I just feel like there's no substitute for considering each goal individually.
Also it sounds like a hard UI problem that could add to the general confusingness or clutter if not done right, not to mention back-end complexity and bug-proneness.
Not to say it's not a worthy feature and I suspect we'll want it eventually. I'm just not exactly rooting for it to win now.
Feel free to change your votes if that was convincing or make your case if not!
PS: That's very flattering that you think we're so pretty that no one's voting for "aesthetic problems" so far. I guess it's a bit vague and general but I do think there's important stuff to be improved that's arguably mostly aesthetic, like the layout of recent data.
PPS: I guess the lack of votes for aesthetic problems could also be like "oh you're ugly as sin but let's worry about that after you get the functionality nailed down".
