Love this enhancement proposal? Give it a 👍. We prioritise the proposals with the most 👍.

Start with the linked argo retry and argo resubmit command documentation and compare their described behavior with the attached UI screenshot. Locate the UI entry points for these two actions, then define hover text that clearly distinguishes when to use each; done means users can tell the difference without consulting separate documentation.
