I know how to use "group", but there are times when I want to move something and it grabs part of the background instead. Is there a way I can "pin" the background colors/objects down so I don't grab them by mistake?

I hate the fact that you have to ungroup an object in order to make changes to it, so I try to group my objects individually and move them around on top of the background, but then it grabs background objects instead.

Thanks in advance for your help.
