Selecting Non-Planar Polygons

To my knowledge, Blender currently lacks a function for selecting non-planar polygons, which complicates mesh inspection after retopology. This feature is essential and would save a significant amount of time, especially when checking clothing after retopology, where non-planar polygons can easily occur.

This needs more information with illustrations or working examples to understand what you mean here.

I agree, there is already split-non planar but select is missing

After reading up on the usage of the split non-planar operator, I wonder is there another reason to still need to select them without doing the automatic splitting of those faces? It would seem to me as someone not using this feature to be the whole process in one operator already, but is there something else to it? This is the first time I had actually heard of it before after being a long time blender user so it is intriguing to me.

Typically on non-planar I rather flatten than split. But there but is an operator for it actually. The other case is inspection but this is very niche, you may be right
