Yeah, I've noted these since I resumed some work on the ORR a couple of weeks ago.

Actually most of these only impact the dev environment itself (not the generated web app). I gave these upgrades a try a few days ago but it was starting to take much time, that unfortunately I don't have at the moment. Let me know how it goes if you want to go ahead with this.
