What is the feature you would like to see?
Stellar contracts export their comments into the interface which allows downstream clients to provide rich documentation on how a contract behaves. From my observations all of these comments are missing in the current repo. I would love to see these added so that downstream clients have an easier time making heads or tails out of a contract's interface.
e.g. here's the SAC interface with detailed comments
