+1, I would like to develop this project a bit more because it's useful.

Temporary I'm making a fork to make improvements, such as the implementation of autocomplete based on a schema.

EDIT: I've tried but Atom API is so strange for me :/

@apupier If you're interested in contributing to this repository I actually made a fork and we together can work some on resolving most important issue actually which is #56. Additionally, I've opened PR with potential contribution notes (#66) but I'm not sure @liuderchi will implement it soon since even PR's from @renovate-bot aren't implemented.
