Thanks for taking the time to feedback, really appreciate it. Some good advice throughout this thread - I'm not going to dismiss the idea entirely but I think for it to useful it needs to be as lightweight and stripped back as possible.

Someone nailed it further down, if you could make a plugin that quickly:

exports artboards from sketch Generate a link Integrate into slack

That would be great - no need to sign up /register or deal with any further additional functionality, far more disposable then a full app.

Maybe make it free or charge a small one off cost...some good food for thought!
