Geometry app three suggestions

[parisse]

I can't speak for HP of course, only for me.
I think there are 2 approachs to using the calc or any scientific software, one of them is commandline-centric and has a small learning curve and the other one is tap- or mouse-centric. This second way will give easier access to designed computations but it will be harder or impossible to make something else and may be hard to adapt to another similar software. This is what you get in many Apps on the Prime, where it is easy to make a parametric plot but not easy to mix the graph there with a graph from the function plot (you can do that with the geometry App or the advanced grapher on the prime) or a statistical plot (you can only do that in the geometry App on the prime).
I think myself that it is more efficient to learn the commandline-centric way, because once you understand it, you will be able to use it to make things that the designers of the UI did not necessarily think about, and you will also be able to learn any other scientific software quickly, something that is certainly important for people buying a Prime: we speak of an expensive calculator here, twice the price of recommended calcs in highschool - at least in France.
(By the way, the geometry app could be part of the process of learning how to write commandlines, create an object in the PLOT view, then look at the translation in the SYMB view.)
As for the PLOT interface, nobody pretends it is perfect, it can certainly and will perhaps be enhanced, but I don't consider myself that it is the essential point to consider when comparing it to other calc geometry applications.
