The reason I fell this way is 2.9.5.6 was easy to find your way thru the interface. It was all off one icon and tabbed. Easy Peasy. It worked really well too. It worked with every theme I tried it with including Clean Retina. V3 will not work with Clean Retina because it won’t show the product view in grid style. Wpdev says the theme is at fault and I say V3 is the problem because 2.9.5.6 worked just fine. I don’t have the desire or time to want to fix either the plugin or the theme.
Along comes v3 which is your old pro marketpress revised to be a bit more fancy. The interface is split up meaning more clicks to find things. It is hard to use, the ability to edit products by category via the easy to use dropdown selection box and filter is gone. The reason this was nice was it would show a nice over view of the categories in category order. The new version shows in default wordpress view which if it can be ordered in cat number order I don’t know how to do it. Selection by clicking on the wp cat title works ok but again more clicks and time consumed.
Without the ability to import and export products to the db easily, the plugin is not worth much. I have tried the plugins you suggest and wp-csv which I did use with v2.9.5.6. None of these are easy to use and if you export from them with a db of products, you will see why. Some of the columns for doing variable product are immensely confusing.
Basically IMO if 2.9.5.6 had the calculated shipping options added to it, the additional payment options and the full import and export capability using your templates, I and probably most of the rest of the users would have been happy. It especially bothers me to see things like V3 destroyed my shop, Help and no adequate responses from WPMU.
It is obvious from looking at the full boat of WPMU plugins that WPMU has gotten on board the WooCommerce train which is probably part of the V3 decision.
WooCommerce may still be the biggie in WP eCommerce plugins but 200 dollars for import export module and the many other dings they charge for make it cost prohibitive IMO.
I may switch to Shopify because I can build a shop and integrate it with wordpress and only pay fees not have to fight the formmatting of csv sheets so much.
