Getting Started with OH3: rewriting the tutorial - 1. Introduction

really, hope I have not offended anyone, the UI is great and I know how hard must be developing it. I am just writing as a newbie who needs to understand how to get around and troubleshoot.

Back on the topic with a live example, not sure if this issue OH3 how view textual definition of an Item is linked to that. Integration of the charts in the UI with items: is it supported only if the item is created through the UI for instance?
