Hopefully this is the right place to post this and it hasn't been suggested already but I think it would be useful to add a numeric indicator to the formula tool to show how many formulas are being done with one tool. It would be useful when going back into or sharing workflows that a user would know more than one function is being carried out at that point. Currently I change the annotation to show how many but I think it would be useful if the icon changed dynamically. Below is a mockup of what I think it should look like.
Thanks,
