Components / groups

for years I have grouped before making component. Now I wonder if it’s necessary

No. It’s never been necessary. Just extra work.

thanks

another question. So people in this group know that your question has been answered and no more comments are necessary, what should I do?

You can click on @DaveR 's post as being the “Solution”. I think people earn points for providing solutions, so it’s a nice thing to do.
