Thanks Jon, Can you fill me in on where we are with CI on Testplugin? I don't know if it is a good time to embark on updates to Sean's plugins and if testplugin is up to date enough to use as template? I imagine it is probably good to use, but just checking..

I've been using it for the builds for high res screens and it builds all OK. There will be a change again when CI implement the next step of their changes. But at the moment we do not have access to the correct resource groups, being open source, to make use of them.
