I love smart lists in Apple Music, which allow me to create a list on the basis of multiple criteria. I think something like that in Sunsama would be very powerful: I would love a smart list for open GitHub issues, for issues that have a smart estimated completion time, for all my tasks due in the next five days, and so on. If we had an advanced search (https://roadmap.sunsama.com/improvements/p/advanced-search), adding smart lists on top of that would not require additional UI work.
