A shorter update...

Still wiring the gui, unit, and activation logic. The activation logic will work like this, or close enough:

When a user clicks on the DevRiot button if the currently selected file is a source file then it continues, if the cursor is NOT inside a method then the tests are run. If the cursor is INSIDE a method, the form (that is on the screenshots) reconfigures itself and lets the user add new tests. When the popup is closed then the tests are run...

Back to coding :-}
