I worked a bit more on the Plone addon for the current LibreOffice extensions and templates center and added a first draft for a new module. This new small module would make it possible to create a new extension project and add an extension file within one step using one form. I commited my changes to the TDF Github repository: https://github.com/tdf/tdf.extensionuploadcenter
I’ll work further on this draft during the next days. Possibly a member of the TDF admin team will take care of the update of the LibreOffice extensions and templates site with the improvements.
