Frustrated with the Numbers App

Don't get me wrong, along with most people here, I love Apple products, even if they are expensive. But, I am so frustrated with things like trying to save an existing Numbers document to a new document, that I am slowly moving back to MS Office.
And why O why did Apple think it was a good idea to get rid of the Save as option?
Not really a rant, just annoyed at Apple's logic.

NB I have been using iWorks for a number of years, and been quite happy.
But, IMHO they are changing their apps for the worse.

I think that there's no such thing as a "perfect app". All apps have there +'s and -'s. Of course it depends on what features are +'s and -'s...and how often you use those specific features. Which then can make them BIG +'s or -'s.

And yes...Apple does like to change things.
