Improvements

Create a place to manage yearly objectives and be able to connect tasks to them

Create objectives on a monthly basis, and a ritual for planning and reviewing each month.

It would be great to have planning for quarters

Have your tasks roll to the day you get back from vacation

Expose an API to allow custom integrations with Sunsama

Could there be a section to place templates? I could use Never but not ideal and it will get lost in Someday so needs its own category

Sometimes, I decide not to do a subtask. I don't like it that when I mark the parent task as completed, it automatically marks the subtasks completed too, along with adding their planned time to the actual time, even though I didn't use that time.

Add the ability to set a priority level on a task card

I really like that we can add due dates because I am bad with remembering mine, but there doesn't seem to be much to help keep up with them. It'd be more helpful if there was a lasting visual reminder in both the task list and the calendar of upcoming due dates of uncompleted tasks. It would be even better if, when a due date is selected, we were immediately given the option to pick all the dates leading up to the due date that the task will show up on for future planning. Without any options like these the due dates don't really get to serve much of a purpose planning-wise

The Backlog should be more than a single list of tasks, it should let me organize tasks into projects and columns. Allow the Sunsama Backlog to be a Kanban system itself.
