Use a script loader like yepnope.js, LABJS, HeadJS etc.?
Finish debug.css
Include non-semantic helper classes? If yes, in main.css or in a different file?
Custom boilerplate builder?
EDIT:
I decided not to add a build script nor server-side configs because that's beyond Gridless' purpose. But I'll recommend using juicer in the Make it better section.
Modernizr also will not be included in the main repo.
EDIT2: well, I think 2.0 won't make it now. The only new feature I could think of was debug.css, which is not enough for a new major version.
