In what is now a rare moment when I find myself using ArcGIS Pro it because I'm doing something....really complicated. In this case I have a workflow where I need 2-3 GP Tools open at once so I can perform a repeatable workflow. Yes, I could probably make a model or a python but I don't want @KoryKramer to think I've retired!
Existing behavior: I have 3 tools open, and I bang through them 1-2-3, and I just cycle each tool and change one thing in each of them. Problem is, I can't remember which "Calculate Field" tool I just changed something in and which is the next one I need to change. Sure, they're in order, but what if I had 5 open and I can't count? What if I'm not always going in the same 1-2-3 order? I have to open each tool to figure out what it's doing.....

Sure would be handy if I could see this:

By TEMPORARILY renaming the tool at runtime. Coincidentally I could see this being handy when folks are trying to document workflows with GP history: instead of 10 instances of "Calculate Field", the user could control the display name of each tool execution
