"Finder" changed- not showing items like before. Any way to fix? My Laptop "Finder" not changed

Just recently, maybe after a software upgrade (?), I noticed my "Finder" bar is not showing the normal categories of things I'm used to and comfortable with.

It has eliminated "dropbox", documents, applications, now I just see "All my files" with no way to make any changes to what is showing.

Is there any way I can fix this and bring it back to the way it was?

My MacBook Air "finder" did not change, same configuration that I'm comfortable with, but the desktop Imac did change.

Any thoughts would be appreciated.

Thanks, Annie Hall
