Thanks for the interesting meditation.

I actually like the idea of the "introduce explaining variable" feature a lot. It's not something I can see people use all over the place, but I tend to get quite a bit of bad code that computes long parameterizations as a single expression, so it would be useful to have.

Therefore, I just implemented the feature as "introduce temporary variable" in the Padre editor. I would expect it to be part of the next release.

Cheers,
Steffen
