Simple task management / checkbox concatenation

[fabyx]

Hello,

I'm using Trilium as my personnal knowledge base since 2022, very happy with it.
Today, I'm looking to customize a little the app, and add some kind of "task supervision page".

This page would collect all "unchecked checkbox" (which I only use for action) in it's note subtree and display them, grouped by note title. This way I would have an overview of all my active task within many notes.
I'm not a professional developer, only using chatgpt or claude to help me.
I've tried several things but nothing worked until now.

Should I use the render-note function ? Use the frontend or backend scripting ?

Could you give me some advices so I might build this script and enhance my experience with trilium ?

Thank you !
