If you use de.dev_lab.logging.Logger to standardize your AS3 logging needs, I've got something for you. At Falanxia we've been using SOS Max Logger by PowerFlasher, but recently I've found a great new supplement, which I think is a great leap forward: Trazzle. Let me copy paste few features we love here: * Bitmap logging * Performance monitoring * Multiple Log Levels * TextMate support For us just the Bitmap logging feature was a reason to switch. In case we logged events just via SOS Max, there would be a need to rewrite all logger calls, and it would be a somewhat painful and completely useless experience. Since we use the as3logger approach, it was really easy to add a small Trazzle wrapper. And there was no need to rewrite anything in our sources.
