[Typo3-shop] Developers... please work together

[Rick - Futuros]

I did recently release an other shop extension. (ftrs_products). This is 
an extension on the current tt_products extension.
Most of the extension can be added to the tt_products extension without 
losing backwards comp. I will contact Franz when my schedule allowes me.
But for now i don't think it is very harmfull to have extensions on 
extensions.
