OT - Feature wish list

I've quickly put together a couple of screen shots at 

As it is now the program keeps the display points in a ring buffer, currently of 
size 10, so what you see on the screen are the last 10 positions of the object 
in a train of circles with the current point displayed as a cross.  The size is 
dependent on the calculated apparent magnitude (using the Molczan definition) 
using the qsat.mag and mcnames.txt data.  If you hover the mouse within a 
certain distance of an object it will write details of the object to a textbox 
in the parent form and display (sometimes) a popup tooltip on the graphics form 
showing the name, mag, and distance.  If you right/left click on the graphics it 
will zoom in/out and the limiting mag of the star background changes from 4 to 8 
depending on the zoom factor.

As it is right now the software only does realtime mode.  There are no input 
dialogs for observer location and such, you would have to edit an xml config 
file to change that.  It still is very much a work in progress.

To do what you are talking about would involve playing with the orbital elements 
themselves and keeping a parallel set of display points?  Without going back 
over the SGP calcs would it be as simple as changing the epoch?  Certainly 
possible to do.

I'll try to make a copy of it available in the next week.  What I really want at 
this stage is some feedback on how accurate the display is.
