Hey Bryan - We've closed the Yeti Launch project to focus on the core framework and the ZURB Stack, along with future versions of Foundation like 7. You can follow the roadmap for Foundation here: github.com/zurb/foundation-sites/wiki/Project-Roa…
The newest CLI that shipped with Foundation 6 is easier to install than ever and we found that most developers were using the command line anyways (GitHub). The CLI is the best way to get started!
If you're looking for tools like that, check out Codekit or Koala App
