When I sit down at my computer at the start of a work day, I typically like to plan out the broad outline of my work. This is the three or four major tasks for my day. I don’t want a minute-by-minute plan, just a list of the major items, so that I can check them off as I work, and get to the end of the day without feeling like I’ve forgotten anything.
There are a ton of todo apps and web services available, but they all provide much more than I need. When I factored in how I wanted to learn about writing a Mac menubar app in SwiftUI, the solution was obvious - write my own.
