After many installs/upgrades during I decided to test possibility to tweak scroll_to_errors js to allow autopilot function that would click on continue button if no error displayed during upgrade/install.
it works, yay!
we might also move the release info before the upgrade of main tables:
1/ you would not have to click on continue after main upgrade
2/ admins should IMO read release notes before the upgrade, not after it
if approved needs some controls on release or upgrade confirmation page, I guess we could use global js variable to pass the autopilot switch to current script
