I'm using Joplin for task management, based on checklists (or "inline todos") instead of to-do notes.
For years I had context notes with lists of (GTD inspired) next-actions for that context (e.g., home, work, shopping). Many of these tasks referenced other notes with additional information required for the task.
I'm currently in a tranistion phase into tag-based checklists using a plugin that I'm developing, where tasks are scattered across notes (that contain their additional information) and tags mark actions that are due #next, associated with some #context, and possibly additional #priorities, #dates, #projects and #people.
