todd rme thanks for your suggestions, I like very much the ideas #4 and 
#8. Some of those belong to Khipu but others have to be implemented in 
analitza library. I'm currently in constant communication with Punit to 
help him to understand analitza and Khipu concepts, right now I'm very 
happy to have some help. Also I'm working with a new branch of analitza 
(newplots) and definitly I will take in account your suggestions.

I really hope others members of KDEEdu can offer more suggestions. To 
all, please just think like this:

"what features would you like to have for a math plotting aplication"?

For example: we already have code to plot implicit surfaces and implicit 
curves in polar coordinates (all of this in analitza library, so we can 
use it in Khipu and KAlgebra too)

I've created this page to centralize all the feedback:

http://community.kde.org/KDEEdu/Khipu/Todo

I'm sure Punit will keep focus on that page (to improve his proposal) 
and I always will keep my eye on that page too.

Finally, just to set a distintion: KAlgebra is not about plotting is 
about take advange of some symbolic features of analitza and do basic 
plots. Khipu, instead, strives in manage mathematical objects (suchs 
curves and surfaces) and perform some analisys (mainly numeric but also 
symbolic) over those mathematical objects. So, for example: if you wan 
to draw the area below a curve, you may want to use Khipu instead of 
KAlgebra ;)

Thanks in advanced to all,
Percy
