So, working with proto is awesome, but if you are trying to make a functionnal mockup then you'll need to have a project that gets similar elements from pages to pages (think master page, may be).
Currently, i can only duplicate my first index page, once it's done.
Ideal workflow is :
Create a great index page
duplicate it depending on the number of pages you'll need
make modification to each page
if you have menu items, like links, you manually make on each page.
Make no modification.
Real case workflow is :
Create a great index page.
Add page 2, change it. (article page ?)
Go back to index, and add a link in the menu to page 2
Oh, and on page 2, put a link to index
Back to index, duplicate to make different page 3 (videos ?)
Change, add the links to it on index and page 2 "at once"
Change stuff on index. Change title, duplicate it on different pages.
Yep, that's iterative process, i do, enhance, duplicate, enhance, link, etc.
Right now, i love proto for 1 page sites, but the strength of the pages preview is killed by the no duplicate, no copy paste on one page or one other, no master page that would keep track of the fixed items (header, footer, menu links).
I know i'm starting to ask huge stuff, but wireframe is not only one page, and it has to be editable to some extent, to come back to the client with v2...
