Describe the feature

I got lots of custom categories because instead of grabing all those plugins I love micro managing everything and well, sometime I want to re-arrange my bag just because it's fun. But having to delete and recreate a category seems unneccessery, why not just rename it?

Describe the implementation

When I go to a Custom Category there should be a text field and a "Rename Category" button next to the "Delete Category" button.

This is a good feature request, along with import and export, and color coding. Will definitely implement this.
