Scott, did you find a way to align all objects to the left edge of a middle object without using multiple steps?
The tool will only align the left edges of the left most object, or the right edge of the right most object, or the center, which who knows where that will be until you use it.
You can do what I am suggesting in 2 steps now, but if the tool were set up correctly, it would be one step. That is what I mean by "almost there" with the tool refinement. As I said, I had a conversation with the programmer, and they didn't see the value, that is what is frustrating.
