I've created a patch to order by default article ordering (ascending / descending), let's see if the author includes that patch.
I see two areas for further improvement:
1) Currently, all category headers are printed as , while I would prefer them to be . That would make it much easier to have consisten styling across the whole site.
2) I would prefer the list to look like the default Joomla article list (articles in a category), just with multiple categories rather than for one.
Thank you very much for the feedback.
The patch is in the version 1.10.
I appreciate your help!
What do you mean with your first improvement? Where are kommas(,) and where dots(.)?
Maybe if you have time you can contact me and explain it to me a little more detailed.
Thanks to CSS and the use of styles throughout the plugin, the table can be formatted at will.
Only the final order confirmation and the invoice does not group the child products, but that's not the purpose or fault of this plugin.
