Ok, now show me a single editor that doesn't make whitespace changes when you press tab. I've only ever had issues with vim messing up whitespace on the line I'm typing specifically with regard to YAML, and yes that's an issue but it has nothing to do with YAML. For example, Adding another colon to a string, wrapped in whitespace or not, will often reduce indentation. That's just plain bad behavior, but it's not intended behavior.
