Simple Bundles & Kits

I have hundreds of products that consist of component products and wanted an app that helps me to get the inventory numbers right. After weeks of searching in the app store, I found two apps that can do what I need. And this one here was the only one that offers bulk bundle creation. So I use it and am quite happy with it.
However, one thing is really missing: there are no filters and no other tools/functions in the app that would help you with searching, organizing, editing in bulk or just in any way handle your bundles efficiently once they're created.
