Witch Mac?

Argh. I seldom, if ever, advertise software. But how could I ever have done without this?

I routinely open 5-10 windows in a given application because I'm a bit of a data juggler. Witch from Many Tricks is a very smooth, very useful application. Especially when you've opened a whole folder of PDFs to compare questions from the last ten exam cycles or something.

Highly recommended.
