This is not a terribly important thing, but in the formula tool, the nitty gritty details of the Expression almost never fit into the annotation space. It would be nice if the annotation by default just contained the names of the variables being derived. So, e.g. if I'm deriving "CalcVar1", "CalcVar2", "CalcVar3" and so forth, the default annotation would just be:
This gives a much cleaner (by default) canvas. The same concept applies to the MultiRow and MultiField Formula tools, perhaps others. Just a thought and obviously not very important. Thanks.
