I heard you like faces, so I put a face in your face...

Working on implementing subdivisions right now. One thing I've come to notice is that depending on how the face is generated (ie. via the interactive split tool or cut faces tool), running the same subdivide command can generate different results.

For example, in the instance below, I'm trying to add split each face into 4 sections in the u-direction. Some faces split fine, others aren't affected at all.

Direction-specific splitting. Some faces unchanged.

One solution I've found is to split each face recursively*, rather than in a particular direction. Though this offers slightly less control over how the faces are split, it does manage to affect every face.

*With divisions set to 3 in quad mode, each initial quadrilateral will be recursively subdivided into 4 subfaces 3 times, yielding a total of 4 * 4 * 4 = 64 faces.

Recursive splitting. All faces modified.

While it is possible to implement directional subdivision, it would require the user to refrain from using certain tools in generating the map. Between the two choices, I decided in favor giving the user the more freedom while retaining basic functionality.
