1) Login link for existing users is tiny and hidden
Why?!? I get it, you want new users, but your existing users need to log in too!
2) auto play of video previews.
Netflix, YouTube, Etc… they all do it. I don’t want the movie to start because I clicked to read the full description, or worse on the main screen just because I stop navigating for a second to read the blurb. I don’t want videos in my suggested feed on YouTube to play silently and then start 20 or 30 seconds into the video once I do click them. Does ANYBODY find these useful? Why are they the default behaviors? Who do they benefit? Don’t they just end up costing unnecessary bandwidth? I know that I can usually turn them off, but having to search for the setting is frustrating.
…and don’t even get me started on form validators that are overly strict when they could just strip the unwanted delimiters or white space themselves, or password fields that cannot be pasted, or password rules that make it impossible to generate a random password.
