@sverbois thanks for creating this Pull Request and helping to improve Plone!

TL;DR: Finish pushing changes, pass all other checks, then paste a comment:

@jenkins-plone-org please run jobs

To ensure that these changes do not break other parts of Plone, the Plone test suite matrix needs to pass, but it takes 30-60 min. Other CI checks are usually much faster and the Plone Jenkins resources are limited, so when done pushing changes and all other checks pass either start all Jenkins PR jobs yourself, or simply add the comment above in this PR to start all the jobs automatically.

Happy hacking!

does this need an upgrade step which sets default value to the registry or action options?

[sverbois]

I'm not aware of any link between the "Add item to default page" menu and the configuration register, so I don't think we need an upgrade step.

[mauritsvanrees]

Indeed no upgrade step needed. This modal option is added on-the-fly.
