Some notes on Geometry App

[mcjtom]

Two more questions/issues:

- in Num view, wen Variables are selected, they are no longer categorized. So for example if there are 3 points, 3 lines and 3 circles drawn (not necesserily in that order), Var button will list: GA, GB, GC, GD, GE, GF, GG, GH, GI objects - it is hard to remember which one is which, without going back to Plot or Symb screen to see what they are.

- how can I deal with vectors in Geo App? I think it would be quite nice to be able to demonstrate how vectors are added, negated, multiplied and translated to students there.

Cheers!
