My point is really to start with the most public API as some teams can’t start with the UI if they are not a UI team but since I’m doing this whole thing myself the most public interface is the UI since I should have started there at the start I’m going to go ahead and start there now. Long terms, as with everything else I’m doing here, I will implement multiple versions of the UI for comparison. React, Angular, and maybe Blazor (might give me an opportunity to flex my long dormant C# muscles. I do miss C#).
