[feature] rewriter works even in normal mode

It would be nice to have the possiiblity of dispay field using the "rewriter" output even when PrettyPrint mode (P key) is not active.

Ideally rewriter should have its own "toggle" key.

This is unlikely to happen because of the performance hit of doing it for all log messages. Or, if the rewriting was limited to only messages that are currently displayed, searching would be confusing because you'd have to search for the original message and not the rewritten one.
