Something that would really help me with planning my day is if I could divide it up into segments. For me personally, this would be around my energy levels -- I'd like to assign some tasks to the morning when I'm still kinda waking up, while I'd like to assign other tasks to later in the day when I'm focused, and -- since I use Sunsama for my personal tasks as well -- some tasks to be done once I get home from work. For other people, this might be tasks to be done before/after exercise/family time, or in the morning vs after lunch vs later in the afternoon, or grouped by objective (i.e. I'd like to focus on project 1 in the morning and project 2 in the afternoon) and so on. Ideally, once I've "given up" on morning tasks, I'd like to move them all to the next day so I can then focus on my afternoon tasks, and so on. I would implement this as horizontal bars that can be dragged around between tasks or easily dragged in/out of the view entirely, with a "Send all to next day" button to send all the tasks (and indeed that "segment") to the next day.
