Mega Aligner 3000XT

This script can be used for aligning an object to another through the timeline, or a given time range. You can select the tracks what you want to be aligned (pos/rot/scale) and the interval where you want the script to put keyframes.

It is very usable if you don't want to use the built-in constrains for example when a character has to grab something (which is in my oppinion is a weak point of 3ds max).

It should work on earlier versions too, but I couldn't test it.
