Is there any way to put a home button on the opera interface??
Sure, as soon as you learn proper usage of the question mark I'll fille you in.
My Opera doesn't look anything like the browser layout map
It wouldn't. That layout map is like 10 years old.
it looks more like what is showing to the left as seen here
That looks to be a screenshot of a much more recent version. So that would be more accurate.
Is there anyway to get to the buttons/toolbar menu??
Download and use a version of Opera released prior to 2013.
