Adding support for Ubercart List Position

1. Install draggableviews_ubercart
2. Make sure you assign the "Allow Reordering" permission to any user roles who will be able to reorder products
3. Create a new View
4. Assign filters - "Node: Is a product (True)"
5. Assign Sort criteria - "Product: List position (asc)"
6. Add Fields - "Title"
7. Add Fields - "Product: List postion" (list position may not be the first field in the list)
8. Add any other desired fields. "Product: Sell Price" and "Content: Image" are recommended
9. Set display Style to "Draggable Table"
10. Under Settings for Draggable Table > Page: Style options: Draggable Table Settings, Set the Order Field - Field: List Position - Handler: Ubercart
11. Create a Page display
12. Provide a path for the Page - example: admin/store/products/ordering
13. Set Access restrictions for the Page - Permission: edit all products (or by role if desired)
14. You may also wish to edit Items per page, or add an exposed filter for Taxonomy Term: Catalog (dropdown), Node: Published filter, or other fields

You can use the "Import" feature of Views to create a new view using this code:

$view = new view;
$view->name = 'uc_products_ordering';
$view->description = 'Drag to reorder products.';
$view->tag = 'Ubercart';
$view->view_php = '';
$view->base_table = 'node';
$view->is_cacheable = FALSE;
$view->api_version = 2;
$view->disabled = FALSE; /* Edit this to true to make a default view disabled initially */
$handler = $view->new_display('default', 'Defaults', 'default');

Sevi, I guess you never did add this to the DraggableViews family, but that was certainly my intention behind uploading the code.

I think there are enough similar features behind most Ubercart sites that it might make sense to include that default view code as well... it could be disabled by default, with a line in the readme to tell people to turn it on.
