Hello I think it would very good if Dolphin 7.0.1 will have MultiServer settings. Because as it allows to upload all kind of files it will needs very big space in future.
And it would be good if Categories and Ads Categories and Ads Subcategories will be multilingual. Because Dolphin use very many people from all over the world and in my country people use three languages.
I like Dolphin and wish all the best!
