Right now, as a user you have to pick a projection. So Click, Click, Click, Click, Click...and Click. This is fine for the sproadic user or novice. For those of us who have been using it for a while (at least for me). it would be nice to do the following - put in the EPSG code from http://www.epsg.org/ . So if I am going to projectdefine or reproject some data I can specify 2274 or 2204 (TN stateplane NAD83 Feet or Tn Stateplane NAD27 Feet) without all the clicking.
