This isn't an issue but it would be cool if you would make it easy to start an https server. If one is developing a bookmarklet that needs to be accessed from an https site, it would be useful to be able to server that js file up from a local https server with no caching.
I'll look into this for the next minor point release
Released in 0.3.0.
You can start a https server and it will automatically create a self-signing certificate or you can configure in grunt using httpOptions which will be passed through to node.js' https.createServer()
