I think you need mr.developer, read more here: https://pypi.python.org/pypi/mr.developer
The most important part is probably:
[buildout]
extensions = mr.developer
auto-checkout = my.package
[sources]
my.package = git git://github.com/collective/my.package.gityes, I forgot this important point because I use a tool that manages it.
Maybe it could be possible to make a 'global fragments folder' so tiles could be used in all themes ? probably by changing something in collective.themefragments/src/collective/themefragments/tiles.py at master · collective/collective.themefragments · GitHub
@datakurre : is this doable ?
That's what I meant @espenmn.
So the user could integrate the fragments he wants in his own design with his own fonts, colors and so on.
In my opinion this would be a better approach. But as I said your work on this is great!
