Support for notes/docs for params/endpoints

I was curious about self-documenting my API using Insomnia. having an optional note/text field for each parameter, maybe even define default values where applicable. Using Insomnia as living, intractable documentation, would be incredibly useful for me.

Is that already a future feature, or already partially supported somehow? In the meantime, i have been adding entries to various environment objects, but interested in a more formal solution.
