I recently tweeted about how adding seemingly minor features can unexpectedly snowball in to a significant amount of work. I thought it was worth writing up in...
User interface is actually extremely complicated and time consuming to design and implement. This is a classic example of thinking it's quick and easy but it's actually one of the harder things to do. UI looks easy but it takes a very great deal of work to make it "just work" that well, so in general any idea that involves any change to the UI is not a minor suggestion.
Ah I appreciate the reply, thanks!
