don't understand why he added the "xmlns:tools..."

he seems to explain it very briefly at the end of the video, and as far as I can tell its there just so we can see the text in the preview without it being seen in the app, is this correct or am I missing something?

Yes, this is correct. The previous module, Lists and Adapters also used the same tool to help with preparing the view before testing it.

Its correct! This is useful when we want to see some property in our view but only in the preview but bot when the app is running!
