Enhancement Suggestion: Add node custom input/outpuLabel data to admin ui

In uibuilder, I set custom labels for the inputs and outputs. These show up fine, however, when users go into the admin panel for the node and look at the Appearance tab (node settings on older versions), they don't see the default label.

It would be really helpful I think if the text of the default label were to appear in ghosted text rather than the static text that is there at the moment.
