Feature level switch node explained better inside materials

What does each input node mean? Does “default” still count iOS in it? We need to be able to hover on the nodes and see which platforms are supported by each node, otherwise its confusing for no reason. There is also no documentation about this thing, and its the one of the ways to make sure things don’t crash in specific platforms and optimize well. Would love to get more tooltips provided in UEFN/UE about this inside the material editor
