This one is probably going to become my favourite, inspite of it’s not-quite-so-nice interface.
Features ‘channels’ which allow your outputs to be filtered – helping to cut down on the amount of noise that heaps of tracing can produce.
Very easy to use:

import com.atticmedia.console.*;

C.ch(“caperinCavemen”, “CAVEMAN set clickable”, 1); // outputs ‘CAVEMAN set clickable’ with a priority of 1, in the channel ‘caperinCavemen’
