This feature is super useful in notepad++ for people who are regularly looking at logs: you highlight a specific string, right click, and you choose “color it red” for example. You can do this for a couple of strings and then it is much easier to read the log.
This is not syntax highlighting as these strings are specific to each log file. Syntax highlighting is also useful, but that doesn't help for strings/keyword that change with each logfile.
