What does "dynamic input labels" do?

If you shift-click the edit menu, one of the options is "dynamic input labels". What does it do?

"dynamic input labels" adds the words "with input list:" to the block when you drop a reporter on a variadic input's arrows. I hate both the wording and the colon, but for the sake of clarity we agreed on it. I guess we should take out most of these hidden options anyway. Please don't rely on anything in there.

Thank you

We should have a meeting to which we each bring a list of minor things we hate, and see if we can make trades,e.g., "you can get rid of the colon if I can change the name of block variables." :~)
