Code comments API
Code comments API is available for GitHub and we at JetBrains are actively using it for integration with Upsource, our code browsing and review tool.
A lot of our customers are using GitLab in addition to Upsource, and are constantly asking about the same level of integration with GitLab. Right now the absence of code comments API is the biggest obstacle for us. We'd like to be able to read all comments (notes) in the code files, and also create/edit/delete a comment on the specified file at the specified line.
