Yikes - the way we have to edit Inventory Categories is really awkard and clunky. It's impossible to add a bunch of categories quickly, I get update errors and have to refresh the page, then collapse each level so I can see the one I'm working on more easily. I realize this might be a big change, but it would be SO much easier to have the option to 'add new category' from the category drop-down list in the Inventory item screen, or just a more intuitive, cleaner interface. The current system drives my OCD batty.
