Xcode - if you ever fancy coding something in Objective C for Mac or iOS Fontlab studio - making fonts Pages, numbers - OSX's cheap and very user…
Coda looks cool ... is the output window when you run e.g. python code on the side or below the editor? because almost every editor I tried so far seems to have the output below (with no option to change that!!!), which sucks on widescreen displays. especially the one on the macbook air.
