On the one hand, great to see such a huge release for Vim that brings so many features people have been begging for. Especially Async IO and JSON.
On the other hand, I hope Vim just become more stable and performant while not introducing new features. At the same time, I hope more development could go into NeoVim, and more people could start using it and writing plugins (not in Vimscript) for it. I want Vim to be my backup editor -- always there and reliable, and Neovim my working gear -- great features, joy to use, could have a few bugs that don't affect my workflow too much and are a natural result of fast-paced development.
I know this sounds really unfair to Vim devs. I'm sorry! I really appreciate the works you've done to make Vim amazing. But I feel for me, I just want to spend 95% of my time on one editor. Now I'm on the NeoVim boat, I feel like having completely switched my workflow to Atom from ST3, and just learned ST3 is going open source.
