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)
Point transforms rotate () or translate () a "point" (vector)
eval_pigment () Insert Menu item
now () Example usages for timing parsing
trace () Insert Menu sample code for tracing an object. Also, tutorial graphic.
orthographic Insert Menu camera setup with explanation of pixel size in POV-units & "zoom"
macro names Some macros ought to be renamed for clarity, or have alias macros that call the poorly-named one
Use cases Certain features or keywords are hard puzzle out the proper syntax and method of usage
Sorting I have a lot of sorting macros which ought be made into a general-purpose include file
Array macros Various macros that make using arrays easier and more versatile
srgb An extensively discussed topic that could use a comprehensive macro for proper color conversion
GitHub repositories There are various GitHub repositories of code that ought to be implemented as include files, etc.
Wiki accounts These need to be expanded and made more accessible from the main forum
Barycentric coordinates These can be exceedingly tricky to implement. I have a series of macros to perform specific operations in triangular space.
Stacks Myself and others have useful macros for pushing, popping, inserting, and deleting from a stack.
Pipes
Normal maps Functions and macros for generating normal maps
Vector swizzling These need to be implemented in source, but for now, practical work-arounds need to be invented
Prism macro for 3D vectors Prisms only use 3d vectors. It's a pain to convert 3D to 2D. Maybe a macro to automate the process.
reflected ray macro/function I have a macro to calculate the direction of a ray reflected from a surface
