Just as this article over at Macworld describes, I sometimes get a lot of Growl messages on my screen. Removing them is very tedious, but by pressing option as you press close on one of the messages, all messages are removed. Very handy.
In this blog I will post useful information that I come across within the technology sphere. As I mostly spend my time on OS X, the majority of the post will most likely be about the Mac platform, but anything that I find useful might be subject for a post.
