Hi, sorry I missed these replies. The search feature for admin is cool. I will add it in next upgrade.
I just installed it on a new demo here http://www.newshopinabox.com/demo you can see it by clicking the Oil and Lube button or the Printer Ink & Toner
There are a few issues such as session id causing drop down boxes not to work, there is also a bug preventing the 'No Items Found' message form appearing sometimes. There's also some small issues in admin i need to clear up, most likely this weekend it will be done.
If you have any other suggestions please let me know.
