It would be nice if legend had the option of some default locations you could
choose instead of entering specific coordinates, like "topleft",
"topright","topcenter", etc. based on par("usr") coordinates. I know I've wanted
it so often I've made my own simple non-robust wrap-around, so I don't have to
remember or parse the xjust and yjust options necessary to make it work. Of
course there should be the option of entering in your own coordinates. 

Also it would be nice to be able to put a optional title inside your legend.
Currently I just make my title the first value in my legend vector, and then fix
the other options so no symbols plot next to it. But this isn't always a pretty
result and can be a pain if your symbols are complicated.

Thanks,
Elizabeth
