No worries, glad I can create things people find useful.
Re: testnet. I've never actually used the test net. Steem.js (used in the boilerplate to retrieve data) can switch to the test net with a single call to steem.api.setOptions(). As for Steemconnect SDK, I've just had a quick look and I can't see any information about using it with the test net. Personally, I just make live calls from a test account but that's certainly not perfect.
