I have a 9-5 day job, and all those tasks live in one category. I also have a ton of other work I track in Sunsama, that live in other categories - namely, one for my side business and one for all other life admin/care tasks. I would love for time estimates to show on my calendar in a way that gives me a "second shift" - showing how all my day job tasks fit before my 5 or 6pm work shutdown time, and then showing how all my other tasks fit into the evenings.
