[Product-Developers] Can KSS help in my use case ?

[Nathan Van Gheem]

Giovanni,

    If you've done all this with your own js before, you just just do it
with straight javascript using jquery and a browser view for the ajax
calls.

    No need to use kss.  It'd probably make it more complicated.  As long as
you know javascript well, use it.  It'll make your life easier without kss
IMO.
