I think kbin also needs a collapse post feature, or ditching the paginated comments and implementing endless scrolling comments instead. Reading comments on mobile when the original post is long can be a hassle coz viewing comments on next page basically reloads the whole webpage and I'm back to the top.
Edit:
And an easier way to subscribe to magazines from a different federated instance. Right now I have to go to their instance, copy the "email address" and paste it to the search bar on kbin, replace the first "!" with "@" coz the latter is the one used on kbin, hit enter and click subscribe.
