Dear Rize Team, As a new Rize user, I've found immense value in the detailed category system that allows me to track specific activities like Learning, Documenting, and Coding. The granular insights have helped me better understand and optimize my time usage. Feature Request: Hierarchical Category System I would love to see the addition of customizable parent categories that would allow users to: Create broad, overarching categories (e.g., "Education," "Professional Development," "Entertainment") Group related specific categories under these parent categories View time metrics at both the specific and general category levels Use Case Examples: Education: Learning Documenting Research Online Courses Work: Meetings Project Management Coding Email Communication Happy holidays and best wishes for the new year!
