I think this could be a good feature, but I guess will have to code it yourself. You could write your own Layout class or extend e.g. PatternLayout. Let ignoresThrowable() return false, and handle the throwable yourself. You will have to construct the magic that filters the lines, maybe by instantiating an implementation of ObjectRenderer that renders a Throwable, or by defining the filtering with a pattern similar to the formatting patterns, e.g. %-3T could mean "show the 3 first lines of the Throwable stack trace".
