Handy AutoCAD-9. Optimized Align
Very useful and frequently used AutoCAD command align has extra inputs you would use occasionally (some situations in 3D modeling), if ever. Normally two source points and two destination points are enough. New optimized align command GN is faster: select objects, then pick 4 points - done__. Two lines in input (highlighted) eliminated.

That LISP has also GM command Rotate-Align (when 1st source and 1st destination points coincide)
