Hi Neil,
I'm really glad you liked the upgrade notes article, and I'm also really glad that you supply your own notes about the upgrade process.
I added a section for the Application Configuration Manager, but regarding the TreeView and image sizes, I do not think this is the correct behaviour for the TreeView, so I opened a new issue on that subject which you can track here. If the issue gets turned down (as a Won't fix), I will add the node.
Thanks for your contribution,
Palli
