I have been playing with CI4 and really like the Kint Debugger. It is activated from index.php by setting $useKint = true; // default === false;. 

It is very useful and has so many unobtrusive features. It is a pleasure to use. 

Simple usage is to add d($variable) anywhere in your PHP script. The browser page renders a small check box with a plus-sign. Selecting the checkbox reveals comprehensive details of the variable selected (which can be a variable, array, object, etc). Toggling again hides the displayed information. Simple and effective. Further details from:

Great choice and congratulations to the team.
