Vim, we consider not fixing our UI issues a feature! No seriously, a text editor that you need to learn how to use is not really excusable in this day and age, the only people using it are the same old-guard Linux users that constantly block changes that would make Linux accessible to the masses. It's the same mindset that keeps Linux niche. Now, I'm not saying there is anything wrong with that, but it exemplifies the way Linux and it's associated open-source applications (mostly) are designed.
Now if vim used an interface similar to edit in DOS I wouldn't be complaining, that was simple but intuitive.
