This page contains some suggestions for GLE improvement. If you are interested in implementing one of them, please do not hesitate to give it a try. If you need assistance along the way, please contact the GLE devel mailing list.
Add in more special math functions and fitting routines.
Use Bezier splines for drawing smooth function plots.
Add support for user defined filling styles and gradients.
Improve the looks of 3D plots (e.g., add shading). Plotting of surfaces that are implicitly defined as f(x,y,z) = c. Add something similar to xg() and yg() for 3D plots.
Add support for arrays and matrices (we are currently looking into this).
