I worked during the last two days on an extension of the Plone add-on collective.addons. I added a new mail form to contact an owner of an addon project to the product. This mail form is linked from the project pages yet. The form field for the project, whose owner should be contacted, is already filled by default. The screenshots below show the link to the mail form and the mail form itself.
I published a new release of the Plone add-on collective.addons on the Cheeseshop (https://pypi.org) today:
https://pypi.org/project/collective.addons/
The release number is 1.1.
The source code is available from the collective Plone Github repository:
