I started using Atom at work recently (I'm a vim aficionado), there are things that I wish vim could do, but the lack of modes and the (as of now) limited capabilities of vim-mode still make me want to go back. It's been the very same experience with previous editors like SublimeText or TextMate.<p>But I really wish someone could produce a modern (like Atom is modern) version of vim, I really do.
The composability of vi/vim is not only its power, but its weakness. It's like a non-redundant language in which (almost) everything can be validly interpreted leaving no room for error detection. In vim nearly everything can be interpreted as a command and executed (sometimes even without strong visual feedback to be noticed) which means a lot of rope for mistakes. And mistakes human do. And for (such imperfect) humans editors are.
