Very happy to hear this! I am very happy with the plugin in its current state. The most pressing for me is to actually make it work in the new version(s) of IntelliJ. Nice to hear there are new features being developed but personally I only use the editor/refactoring features. So I will leave it to others to feedback on those. 
Now that I think about it. Since I use the “External Tools” thing to run builds etc in the console I would like it if errors shown there would link to the file/row. (I tried to set that up myself some time ago using “Output filters” but had no luck.)
Anywhere one can find a build to test?
