I created already a new Plone add-on for the upload and management of office template files during the last weeks. I made some further changes to the source code of the add-on during the last days and published new releases of the software.
I reworked the edit view for template projects today. I gave it another structure with register for the different content parts. The dialog is much clearer yet and that will help a contributor to finish the dialog much faster and submit his new project (or edit one of his / her projects).
Here are some screenshots of the dialog and its register:
There is another register for the optional upload of template files for different platforms. It looks similar to the above one. There is also a register to upload a screenshot of the template. This screenshot will be shown to the user in the template project view.
The source code of this Plone add-on (collective.templates) is available in the Github repository of the Plone community:
