Some notes from Alex, regarding bugs and usage: - Autofocus in intervalometer: in Full Auto mode, it does autofocus, but in A or M it does not (at least on my camera). Tou may also switch the lens to MF. - Zebra overwriting Canon menus: should be fixed in latest pre- release, but this slowed down a bit the drawing routines. - GlobalDraw: turns off zebras, cropmarks, spotmeter & audio meters with a single click. - Live View bug is still not fixed, sorry. - Save Config is also safe to use (and you will usually want to use it). In fact, from the debug menu, the only potentially dangerous is draw_event (it is sometimes unstable on my camera). Not sure about the items in the Boot menu... Powersave should be safe as long as you don’t forget your camera on :D
