17787 oscommerce/ajax mods

I have a CRELOADED 6.1 (oscommerce based) site that sells access to online video lectures. Some are downloadable and some are only streaming. After purhcase, the customer gains access to their list of lectures by a link named "MY DOWNLOADS". This is what I need. 1. I need my MY DOWNLOADS page to be both sortable and searchable. I would like to add the ability to sort on criteria such as Category, Name, Date purchased, etc. The sort options should be able to be savable as a preference by customers (ie a button that says "save my sorting" that saves the configuration of sorting in the DB) Could we have multiple filters for the sorting? This programming could be based on a "live grid" type of mod. The searchability should be by name of the product and would ideally involve AJAX to allow for an "instant search". I can provide you with a mod for this that we can incorporate. I would also like to develop an AJAX mod to allow the user to create a "bin" for their favourite lectures by doing adding a "drag and drop" feature to the download list. (Again I can show you an AJAX framework we can use for this.) 2. I need the ability to modify the field "download_count" (this determines the number of downloads left) in table "orders_products_downloads". This could be a simple addition to the edit order page on the admin side. Should be easy. 3. I need the ability from the admin side to reset a customers password to a set word like "testing" for the customers that either can't figure out the forgot password function, of the email was blocked by their ISP and they can't login then.
