I'm doing a lot of vertical stacking within an artboard, though still evolving my overall approach.

I've had some success creating a 'global' artboard that sits below / around a number of smaller artboards — the first is exportable for reviews/printouts, the second for easy export into prototyping apps.

I like to think of these categories whenever I'm looking at a subset of mockups: • Sequences - representing a flow, generally for most common uses ("Sign Up"). • States - often 'edge cases' or variations that need documenting but don't require a flow surrounding it ("Password denied"). • Responsive sizes - re-presenting the same content across different canvases. • Alternatives - exploring one of several solutions (might be a singleton or its own set) ("Sign Up - modal" and "Sign Up - inline"). • Versions - a specific improvement to one of the above, or to mark a milestone across the entire document ("v3 - post-user testing").

As a old-school Fireworks user, I used Pages for high-level version control and States for everything else, though using less of the multiple onscreen artboards paradigm of Sketch, which seems to work best for mobile app/site design, and less so for desktop.

To add to the artboards, you can leverage the usage of symbols for elements that are consistent throughout. That way if you update one it updates all.

If you need dynamic text inside of a symbol, you can always look to https://github.com/tisho/sketch-plugins/tree/master/Symbols which works the same as native symbols but with a keyboard shortcut and the added dynamic text.

I tweeted Bohemian Coding a similar question today, curious about how they best recommend doing this.

Basically looking for layer comps, but perhaps a version that aren't so finicky to deal with.

At the moment I just toggle the states manually, but it's far less than ideal.

Instead of creating new page you could just create new artboard inside the existing page. I think that makes a lil bit more sense..
