Just dropping this all here as an all-inclusive to-do list. Feel free to pick up a project and research or develop it as far as you're able.

Function graphing					I have a system to graph equations.  I think it might have a few axis-labeling bugs, and needs texting and fixing.
Parametric mesh						Takes parametric equations in x, y, and z and creates quads that are composed of 2 triangles.  Can stepwise cycle through parameters.
Parametric mesh2					Same as above
Read / Write to/from file				basically just want a simple Insert Menu item to drop functional code into a scene	
Isosurface Evaluate					Same as above
Heightfield correcting macro				Newsgroup discussion implies that an Insert Menu for generating properly formed and oriented heightfield from function code would be desirable
Image_map in memory from a function			
Analytical Geometry include				Just would like Friedrich Lohmueller's include files to get cleaned up, formatted, and clearly commented as to purpose of each macro
irid							Good looking iridescence can be tricky to implement, so a sample scene would be extremely helpful.
3-point lighting					Warp had a good tutorial.  Having a macro to set up basic 3-point lighting would help new users a lot
transparent background					This is a very frequently asked question.  Make the fix an Insert Menu item (comments)
Data structures						There are a lot of useful data structures that would make writing scenes so much easier, or even possible
Vector math						There are lots of clever things that can be done with matrices, determinants, vdot and vcross
matrices						Need actual mathematical matrix methods to add, multiply, exponentiate, Gaussian elimination, transpose, eigenvalues, trace, ...
Solve geometric problems				nearest point to object, intersections, 	
Scene layout tools					Grids, object locators, special light source diagramming aids
Matrix determinants					for any MxN matrix
Minimum visible sphere radius				How to set up camera so that a sphere completely fills the viewport - extends edge to edge of smallest dimension
Analytical tangents between 2 circles			I have an extensive system to do this and also create a prism from an enclosed path.
Numerical pigment patterns				I have hundreds of equations to make pigment {function {}} patterns
Catenary						It's unclear if we have an easy-to-use macro that is mathematically correct
Full-color pigment					Insert Menu item to make an average pattern rgbft pigment
f_Identifier - function					For large, complex scenes, sometimes it's easier to have a system of naming identifiers as to type
v_Identifier - vector quantity						
s_Identifier - scalar quantity						
C_Identifier - color						
P_Identifier - Pigment						
T_Identifier - Texture						
L_Identifier - a loop variable: #for (L_Identifier, 0, 10)
