When it comes to editors, there's definitely a big spectrum of how much it does vs how lightweight/simple it is, and I think Sublime Text, for a majority of my usecases at least, is in the sweet spot.
Don't get me wrong, full fledged IDEs are useful sometimes too, but every time I go to use them, I always spend half my time searching and fighting the program instead of being productive. That's what I mean by Sublime making programming fun. Things don't get in your way and everything is very clean. Sure it may do less, but at least it doesn't drown you in features you don't use either.
