Nice idea but needs a comment system. For example, I know a pattern like this has problems: http://dbpatterns.com/show/5072096089cbad6a389867c7/ http://dbpatterns.com/show/5072096089cbad6a389867c7/ Change the price of a product then calculate last months revenue. I'd also like to see a brief about what the pattern is trying to solve and why it is the way it is. I've used patterns for sortable hierarchical categories before which is more complex than a parent/position relationship. That would take a bit of explaining with regards to querying, sorting, inserting, removing records. But all in all, I like it. Nice clean UI and can see it growing.
