Why Cs-Cart Marketplace Is So Hard To Use?

1.I'm not a programmer, when I want to find some add-on in the marketplace, is really hard to use by search if i don't know the add-on name, but i know what functionality i need, can you guys improve the category of marketplace??? to be more specific, before i was using prestashop, their marketplace is really good, is easy to find the modules that i want to use. really hope CS-CART company leader can see this MSG ,and start to improve your marketplace!

2. is there any add-on that like channelsale? is an aggregator for marketplace, CPA platform, but this one is for American market, i need a similar product that suitable for Russian market

3. is there any add-on that can provide solution for dropshipper? for supplier side in CS-CART?
