Todoist: Improved Todoist Integration with Selective Task Import

Akiflow would benefit greatly from deeper Todoist integration, especially the ability to selectively import tasks (e.g., via tags) rather than entire projects or lists. This would allow users to keep a large backlog in Todoist and pull in only what they’re ready to act on—helping reduce overwhelm and avoid the stress of seeing too many unplanned tasks in Akiflow.
