Great add-on! Rated 5 out of 5 stars
Wow--thanks for this! I haven't used all of its features yet, but based on the functionality and interface, I'm sure it will be of tremendous use.
In response to the review by the vegan, below, it is, in fact, possible to rename any category. And you can delete individual items and add others as well. If renaming hasn't done the trick, once the category has been emptied of items, it's easy to delete the category entirely.
