One thing I noticed today, which was never much of a thought before, was how to straighten curved or uneven edges along a loop.  I noticed the 3dsmax artist using "Loop Tools" (which we also have in Blender!), with a function called Straighten, which automatically made the edges along an edge loop planar with an axis.  I tried several methods to reproduce this function in Blender, but our version of Loop Tools does not have the same Straighten feature.

I ended up using snaps, then scaling the selected edges along an axis, which required some precision and patience, until they were straight.  This worked, but wasn't exactly easy to accomplish.  Some research on Youtube showed that other options involved using the Flatten feature in Loop Tools, set to View.  This also worked (sort of), but wasn't exactly accurate in all cases, and required a lot of orbiting and precision.  The only other option I found seems to be using Relax in the Loop Tools, on the vertex path of the edges you wish to straighten.  Change the Interpolation to Linear, and increase the iterations to a high number, then enable "Regular".  Lots of steps there.

Does anyone know a faster, yet precise, way to do this operation?
