Is there any recommended editor to use since IntelliJ seems to choke on native library definitions?

Internally we use IDEA for development of Kotlin/Native, and we are working on dedicated IDE for Native

Try Atom (https://atom.io/) with the file-icons, linter, linter-kotlin, git-plus, script, language-kotlin-ide and language-kotlin plugins.

@napperley Can Atom autocomplete based on shims generated by konan?

Not sure (haven't tested). Best to try by installing the autocomplete-clang package (https://atom.io/packages/autocomplete-clang) and using a small C lib as part of a basic auto completion test.
