Steps to reproduce the issue

Activate debug and the debug plugin

Expected result

The debug bar displays at least the same information as in Joomla! 3 or an improvement.

Actual result

A selection of missing information:

• call stack (most time the correct line where the query is executed is shown, but that information is useless when the query is build somewhere else (e.g. \libraries\src\Table\Table.php)
• Explain information (One could copy&paste the query to phpmyadmin etc. but that slows down working with the debug)
• Profiling of the execution (still could be copy&pasted to phpmyadmin, but there are probably the information different)

Additional comments

I also think, the debug bar could be improved with some colors, to identify slow queries, or sum ups faster.
