If you use an entity in a microflow, the default name for that variable or parameter is the entity name itself. When you rename an entity, the variable name will retain its previous value of the old entity name. I propose that if you rename an entity, Studio Pro searches for any uses of that entity in microflows and if the variable or parameter name matches the old name, rename that variable to the new name. Also do this if it's prefixed ‘New<Entity>’. This will save a lot of time when refactoring often-used entities.
