Good Xavier,
mass actions is a great tool with a lot of possibilities that would satisfy a great number of your customers and for sure help many to migrate from other platforms to HikaShop.
Creating some clear extensive documentation so others could develop with ease their own complementary actions as we do with plugins would be really great. I'm pretty sure for my coming developments mass actions will play an important role as there is a huge number of old outdated websites out there that sometimes persist in surviving because of the hard work and uncertainties related to create interactions with other corporate softwares. Mass actions can play a great role in this.
To make it simple: this development of mass actions you did these late days will help me bring several websites linked to the one I am developing now migrate to the joomla / hikashop platform.
One more time thanks for your valuable help and commitment to fix the problems.
