Request: Compare Before/After Element Changes

[onomou]

This is related to #16, it would be really nice to have a snapshot of an element to compare with itself after some changes. For example, to answer a question like "What properties of this dimension change when I move it over?" The compare elements feature works great, but requires two different elements. Being able to see changes to an element would make it so much easier to discover what Revit (or the API) is doing to an element in certain circumstances.

That option already exists, it is called "Freeze"

which basically is making snapshot of members of an element at given point of time:

and as you can see, it allows to compare taken snapshot with the current state of the element....

unfortunately it works only with members view, and not properties view at this movement ....
