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.
• Accessible and syncable across PC and Android,
• Freeee....?

Nice to have:

• Sync with Google Calendar/Tasks
• Color-coding tasks
