Lady, EVOLVED 
why can't you see who reacted to a post in mobile slack
@Lady you should be able to? long press on the reactji?
@alyssa ohhh
that is a bad ux
@Lady fair. i just tend to try long pressing since so many things use it for random shit. It is always kinda terrible for discoverability tho.
@alyssa i am usually pretty good at trying long presses but on buttons i expect presses to always activate the button not do something unrelated
@alyssa i would never ever try that experimentally because if it didn't work i would probably wind up doing an actual reaction on the post
