Kanban To-do more rich content

I need help creating a better template structure for todos in a Kanban-style task management app. Specifically, I want:

1. Main Todo Structure

   • (important) Multiple tags support (both at main task and subtask levels)

   • High-level task information at the top (there is an in review request already here)

2. Todo Notes Section

   • A rich header area for high levels detail on the task at hand.

   • Ability to generate a summary of key information from text of the note ? (an Ai can take content of the note and organise in check marks/tag/bento boxes info for the header

   • Space for subtasks with their own multi-tags

to better convey my suggestion, I asked an llm AI for help, I'm only looking for the content structure/template design, which could serve as inspiration for the notes section within a todo item. Thank for reading Reda
