Hello,

hard to tell which node change it was, I made a lot during my tryouts 
for the site application. I need to take care of changes from now on, 
played too much around I guess.

I published the extensions on github which functionality I used a lot 
with TYPO3 CMS:

* SeoTool for page title, meta description & robots, Canonical tag
* Galleria picture gallery
* BxSlider for (any) content slide
* BootstrapContent for content wrapping and elements of Bootstrap 3

Maybe someone is keen to join forces and would be nice to get some feedback:
