Terminal.app is very good in many ways, but Apple really needs to work on the configuration mechanism before I can use it regularly. I frequently want to make tweaks to one window, and I just can't stand having to make a new set of Preferences every time a window disagrees with the established settings. Since the sets contain everything (colors, terminal attributes, long lists of key mappings, etc.) there are potentially a lot of things to redo. Also, what's bizarre is that opening a saved file has the side effect of automatically creating a new, permanent set of Preferences. There isn't much point in having files if Terminal insists on re-storing everything as Preferences anyway.
