Agreed. And the Graphics Inspector and Drawing Tools are awfully nice.

The documentation for Show says that the PlotRange is set by the first 
graphic in the list of graphics you are showing, and to see everything 
you should use PlotRange->Automatic. PlotRange->Automatic was the 
default (as it seems to have been in 5.2). No idea why they changed 
this; it's a pain the neck to have to set the PlotRange all the time in 
Show.

Another little thing: I'd like the ability to set a different color 
scheme (perhaps a user defined color scheme) to be used for plots. I 
find that if I plot two functions together without setting a PlotStyle 
that the blue and purply colors Mathematica uses are a bit difficult to 
distinguish. I'd like the first two colors to be say, blue and red.

Agreed.
