Using Atom right now, but the syntax highlighting part is a problem as we don’t have a “language-motoko” package yet. After following this link, I was able to make Atom recognise .mo files as .js files
i.e added the following to the config.cson
"source.js": [
        "mo"
      ]
Not great, but better than no highlighting at all.
Wondering if there are better solutions than this? What IDE(s) are you guys using?
