Does anyone who has found a good workflow with copilot have a good resource to share that demonstrates how to get the most out of it? I really want it to be more useful, but rarely find that it's helpful for completing more than a single line or two. Do you write out comments for everything you're going to do and then just write it yourself if the suggestion isn't useful? Is there a trick to getting it to read your code itself across files?
