I will be honest, I am not Mr. Flowcharts which is really who Lucid Charts is directed towards. Even so Lucid Chart offline app and the Lucid Diagram Google Doc add on are pretty cool. I am using the same group account (teacher / student) that I used earlier for Lucid Press.
I think the Lucid Diagram add on for Google Docs is great way to integrate Lucid Chart into Google Drive. I was able to save the document I created in Lucid Chart and insert it directly into my Google Doc. This is exactly the type of integration we need when working in the clouds.
