Description

It could be helpful to have some statistics at a glance of reported defects.

Describe the solution you'd like

I would like to see something like this in the Summary and similar output in the console.

	👕 Style	🗒️ Note	⚠️ Warning	🛑 Error
🔢 Count	10	5	2	1

Of course, the output will be influenced by severity input. When the severity is set to the warning, the 👕 Style column will be marked as N/A.
