Getting a lot of output is only nice, as long as you know where to find stuff. Imagine the following scenario: You are searching for a specific value, function or property somewhere deep inside a specific debug output "window".
kreXX offers a somewhat advanced search function:
Marking all appearances
Open the collapsed nodes to the output
Scrolls down to each finding
Each output "window" can be searched individually.
There are 4 options to make searching easier:
Case sensitive toggles the case sensitive of the search
Search short results
Search long results
Search for a whole value
