Suggestions for a change in Autocomplete - we've found out that the minimum char to trigger the ajax-chosen autocomplete to start working is 3 char, i suggest to make it 2, as there are some cases that admin might sell a brand that has only 2 char such as 3M. Leave the time delay, it's fine.
The file is admin/view/default/template/form/chosen_select.tpl.
Thanks
