I have a question, is it possible to disable the Performance optimization. Do not load all categories for navigation. It can slow down the system if you have thousands of categories.? I can see problem loading all at once with large quantities. But if I have low quantity (<30 in 2 levels) I'd like to display all of them at once so customer doesn't have to go through first level postback to get to the second, I'd rather shrink it wish some javascript so option to disable this would be great. Otherwise great patch, keep it up! :)
