From A Different Angle

I’ve come to love Lightroom. When it was just released I didn’t think I would need it. I figured I could do everything I needed to do in Bridge and Photoshop.
I still do a lot of stuff in Bridge and Photoshop. I do believe that Lightroom isn’t nearly as powerful in some things than Photoshop is, but I’m not sure if I could be without Lightroom anymore. Especially (among others) its archiving and keywording properties are amazing.
But as with all things also Lightroom has some flaws.

With the amount of photography I do (and the systematically annoying perfectionist that I can be), I need to have order in my archives. Thus I would like to create many catalogs.
Yep, you can create a New Catalog and that will clear the slate completely.

But suppose (which is often the case with me) that I want to start a new catalog, but leave some of the (smart) collections that I have? Or some of the folders?
I’d delete everything from the present catalog that I don’t want in the new, leave what I need and then go to File – Save Catalog As…
But wait… what the…??? There’s no Save Catalog As…? How can there not be a Save Catalog As? I don’t know one piece of software that doesn’t have a Save As function, so what were the people at Adobe thinking when they left out Save Catalog As?

That would be the first thing I would expect in one of the new versions of Lightroom.
