It took me a bit of wrangling, but I believe Phase II of the project is now complete! It too me three different UI approaches to managing vocabulary lists before I finally settle on a set of functionality that meets my design goals. It is now possible to add vocabulary lists that are only editable by you. While other people can see this lists and use them as-is for their own learning, they cannot edit them. Eventually, I will add the ability to share lists between people but that is for a future day. Once a vocabulary list is created you can either add words from the list itself, or by browsing words. When editing words, you will only see your lists that you can attach a word. Hopefully the current approach is one that people find intuitive and easy to use.
