The documentation is unclear about what 'position' does in the template headers. I now understand it has an influence on the position in the dropdown (nice!), but I had to discover that through trial and error.

Improve the tier prices feature - add info like "Buy 2 in x.xx$ and save x%"

when running installer

The SQL being executed was: SELECT * FROM configurable'

The database check, and possibility to add missing updates, could go into the update page.

Just reading through the MySQL 5.7 documentation on date/datetime fields (https://dev.mysql.com/doc/refman/5.7/en/datetime.html) and I think we might still have some issues. From that documentation:

 The DATE type is used for values with a date part but no time part. MySQL retrieves and displays DATE values in 'YYYY-MM-DD' format. 
The supported range is '1000-01-01' to '9999-12-31'.
