The sidebar with tasks is AMAZING, however, the colour coding of the task isn't enough for me. It'd be helpful if we could divide the sidebar tasks into visible groups.

Example:
You have two task lists, one for home, and one for work. Right now the tasks are all mixed together and color-coded but randomly spread across the column.
With the grouping, you could see a "home" tasks list and "work" task list under each other and the tasks in those lists for the day in them.
Extra points if you could minimise it so when you're at work you are viewing work tasks and when at home you are viewing home tasks, but that would be super extra.

Another example:
You sort your tasks by forenoon and afternoon, or priority. Your task lists are named accordingly. Viewing them together would help in this case as well.

I function on daily tasks, my life runs on the daily tasks list. This would make navigation through the day easier.
