Any FOSS todo lists with time-blocking calendar feature?
I like todo lists, and I like time blocking so I can schedule out specific hours to work on each task. However I have yet to find an app that combines these cleanly.
Features I am looking for:
Todo list that allows nested lists, and adding details to each item (due date, more detailed instructions, etc.)
Seamless integration with a calendar, so I can assign a given todo item to a date and time
Adjustable time durations. Not every task is exactly 1 hour.
I'm using Tasks.org with DAVx5 (android) and an external Nextcloud hosting.
You can set blocks of time, nested tasks and it adds them to the Nextcloud calendar. I think Tasks.org can sync with Google Tasks, but it has limitations.
