#### Topic: Arrow endpoints for Insert relation; arrow fix for Parametric function

Like other members of this forum I am a math teacher and really like Graph.

When teaching our students we pay particular attention to whether the ends of lines have closed circles, open circles or arrows. (BTW, I wish that Graph also had square brackets for endpoints, in addition to the curved ones.)

New feature request:

(1) Add Endpoints Start: and End: functionality to Insert Relation dialogue for example when graphing x=y^2 or x=abs(y)

(2) Fix the Parametric function dialogue so that when graphing {x(t)=t^2, y(t)=t} or {x(t)=abs(t), y(t)=t} the arrow for Endpoint Start points in the correct direction. It seems that you would need to add a left-pointing arrow to the right-pointing one that you already have. (BTW, choosing the open endpoint (curve) stays the same even after changing in the dialogue.

I could probably get the graphs I'm looking for by combining graphs, but this would be easier, especially when I show graphs interactively to my students in class (e.g., when doing transformations, etc.)

Whatever you decide to do, you've got a great program. Thanks.
