Right, another distraction! I just checked in another plugin that allows to take advantage of the recent changes to the logging code.

The plugin adds support for FirePHP by means of a custom ZMLogging implementation. Pretty neat, indeed!

EDIT: Originally I just thought it would be cool to have something fancy like this. However, as it turns out, even after using it for a day or two I start loving it. In particular with translating the errlevel to something FirePHP understands it becomes a lot easier to browse the log (with the custom error handling enabled).
