Improvements

Visualize your tasks on your calendar without having to schedule them to your calendar. Visualize the actual time you spent on tasks on your calendar.

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

Expose an API to allow custom integrations with Sunsama

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.

It would be great to have planning for quarters

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.

Having the ability to either change the color of tasks.

Show my data across different time intervals of my choosing Show me insights about my data e.g. actual vs estimate

I keep clicking on this thinking it's the Submit button, when it's actually the top/bottom order button. Perhaps there's a more obvious icon for that like a list with an arrow, or a list with the first item having a right caret pointing at it (Apple Music has good ones for "Play Next" and "Play Later", they might work really well here)
