The big issue right now is that there's no magic solution like "just disable it and make it warn by default". We really do have to revisit what do we actually want to show and change the level accordingly. Right now it's too much of a mess, important stuff is "debug" (as Martin originally hinted even new things are like that:-), whereas error/warns can flood way too much. I think what Dan did in networking with the separate file is a good improvement…as it make them/us realize what is important. Though I think we should do it by levels and/or prefixes
We also miss some more flexibility with the current tools (not sure if there are even any), to be able to dynamically change the levels, filter non-related stuff before it gets written…
