I would like to add numerical functionality to this plugin, but have been unsuccessful in getting it to work.
In additition to the A, B, C...Z I would like to add an 0-9 category for names that start with a number. the way the plugin is written to auto create class names from the letters is straightforward but for the numbers I would need to show all items that start with 0-9 under the '0' class. I know what I need to do but havent been able to get it to work.
