I recently came across the following app: wassup.
Wassup is a scriptable terminal dashboard. Configure panes and content logic in a
Supfileand then runwassup.

I've probably followed @joshdholtz since his fastlane days and loved the concept behind this.
Now I can read Ruby but would I say I'm confident in working with it... plus the idea here was to "borrow" the concept and see if I could rebuild it in .... .NET of course.
Now there are libraries out there that can do a majority of the work so I might as well start with using Spectre.Console
Added the sample data just to see what it looks like:

Then tried putting into panels.

Helps if I don't wrap panels in panels!
Next is to actually get data from some APIs... then create an equivalent Supfile to build up any layout you wish.
