Ability to see errors in editor

I had a quick play with this plugin and it's an improvement over using a shell, but it's not very tightly integrated into the editor. It would be great to see a bit of the approach used by https://github.com/leinardi/mypy-pycharm integrated here. That plugin looks like it is not actively maintained any longer, and just getting it to detect the mypy executable is a huge PITA (for some reason it's trying to use my system's python2 interpreter), _but_ the big thing it has going for it is the ability to see errors in the editor, which is pretty slick. It gives you a bi-directional relationship between editor view and error view, whereas with this plugin it seems I have only a uni-directional relationship from error-to-editor.
