Home Assistant is written in Python and this is pretty fortunate I’d say because it is a very beginner friendly language. Personally I despise yaml and jinja as their syntax is confusing and in case of yaml so sensitive to bad indentation. It really grinds my gears. I am a developer and would love a simple editor in which i can write scripts and automations. i know that there are HACS integrations for that but I feel like a native version would be really beneficial, especially if there is intellisense for autocompletion. The Automation page was always pretty clunky and the redesign in the latest update is miles better but the simplicity of a good text editor always is best.
Maybe give the User the choice of choosing between VSCode or for the hyper nerds a Vim integration.
