Possibility of displaying a number on the drawspace?
Like floating text, say a point telling the user its coordinates, or showing the result of a function?
I second this. In addition, it'd be cool to display LaTeX via labels, too. Would help for quickly displaying greek letters (particularly when they are wanted on axes), making things generally look fancier, displaying complex notation etc.
Desmos has this functionality built-in (see https://www.desmos.com/calculator/grnyncarek). Doing something similar to their implementation would be cool.
@o-b-o If you haven't found it yet, there are static labels. See https://www.math3d.org/labels
They're not dynamic, so you can't show the coordinates of a slider, etc, nor does it support LaTeX. Both of those would be great.
