Skuid Importer: Download a Sample File not working....

First of all, based on this post:
https://community.skuid.com/t/import-child-objects?topic-reply-list%5Bsettings%5D%5Bfilte…
The Skuid importer is much more awesome than I knew.  I did not know you could pass URL parameters using merge syntax… that is super awesome.
On the import page, however, the “Download a Sample File” link is dead. It looks like based on the image on the page that the column headers should be field labels instead of field names. Is that correct?

Also,
1) preferably I would be able to suppress the Salesforce header. 
2) Display as inline frame in skuid popup / panel
3) Have an “Importer” component in the page builder
