Auto-update database structure on update failure
Joomla Toolkit will report a failed core update on certain occasions (like running out of memory). It will then ask to check the site manually.
This "manual" check translate into checking for issues with the toolkit, and pushing a button to update the database structure. It's all done from within JTK.
The purpose of the toolkit is to automate such tasks and report the issue accurately, so upon failure it should re-check the site and resolve the issues automatically, and only report the need to check manually if that fails.
This is a valid idea. We will consider this functionality in upcoming releases if it will be popular.
