Result: (The new link's location is circled. The link label has since been updated to "Edit template data".)
Original task - feature proposal:
The current workflow to get the TemplateData GUI can be quite convoluted:
- Edit the template page
- Observe the warning that the data is probably transcluded from Template:Foo/doc
- Click the link to open Template:Foo/doc
- Click edit
- Click "Manage TemplateData"
or
- Find the TemplateData section on the page
- Click the section edit link
- Wait for the editor to load, then press "Manage TemplateData" button that appears late
A better workflow would be to add a small edit button to the output of TempateData that opens the editor on the correct page (e.g. /doc) and launches the TemplateData GUI immediately. This would be similar to the extra edit links wikis sometimes add to template invocations to edit the template itself.
One could also add a "TemplateData" button to the edit tabs.
