After years of wanting way to quickly convert components to group I finally sat down and got it down. This can be useful to turn components into unique objects before performing a solid operation on them /given you don’t use the native solid tools that don’t honor components in the first place).
Awesome! Thanks! 
I can see another great use when importing Revit models into sketchup. For some reason Revit exports each entity as a component (when using the dwg workflow which I have found most efficient), which can be very annoying (for many reasons)
Being able to convert multiple components at a time is going to be very useful!
