"Radical Candor" calls it rocks & rock stars. You need steady, reliable people, who are happy excelling in their current position (rocks) just as much as you need highly motivated people looking to work up the ladder into leadership positions (rock stars).
You can drag edges, but it doesn't seem to have a concept of a "square" beyond the tool itself. So after you've placed it, you can't move individual shapes around. The select works more like a text-editor's highlighter than something like the lasso tool in draw.io
My first thought is this would be a great chores list for parents to set up for kids. Does it have "flag flipped at x'oclock" type logging? An option to require/allow an image, or flag-creator-approval would be cool too.
Are there any themes that change when linting/tests are passing? I think it would be fun to add a glow to your text if everything is working well. Or only add glow to areas where you have code coverage.
