Thanks for the rapid reply. First, sorry for the length of this reply. The tldr; version is that I'm providing a list of features that I would have to add for my employer to be able to use this rather than the default Ebay interface.
So to clarify, if I have custom meta fields that I have created myself (and don't belong to MarketPress by default), I can access them by using, for example, double-bracketed [attribute_circa_date]?
I like the future flexibility that you're talking about. However, I can't use WP-Lister in its current form for my employer because they have so many special requirements and find the default Ebay interface more convenient because of the minor functionality loss with the use of this plugin. They sell antique furniture, which is a pretty unique and under-served industry as far as it relates to ecommerce applications. For clarity's sake, I've made a list of things that I would need to change in WP-Lister for my employer to be able to use it and still keep the functionality and convenience that they have using the default Ebay interface:
- The ability to add shortcodes that refer to functions and not simply custom meta attributes; for example my client uses a template that places product images in a table with captions, so I would need to add a shortcode, e.g. [wpl-gallery], that outputs this table.
- The ability to modify the base product price by a custom formula that takes input from weight. For example my company uses a formula that takes their base price, multiplies it by 1.67, adds a shipping cost based on the weight, and then applies a discount based on whether or not the user is logged into the website as a wholesale user (which receives an additional discount). Lastly my company uses a slightly higher price on their Ebay listings because they have found that Ebay customers never buy their products outright but always choose to make an offer. So the store prices are lower and not consistent with Ebay prices, thus the need for a formula.
- The ability to choose Freight shipping. My employer ships everything either by UPS or by Freight, which is not in the list of available shipping options shown on the Profile editor page.
- The ability to leave Condition on the Profile editor blank. Currently the only Condition option is "New," which isn't accurate for the wide array of antiques that my employer carries.
Lastly I am guessing that your plugin works with WP-Ecommerce but not with MarketPress? There is no "Prepare listings" option in the bulk actions menu located on the Products page.
I will contact you via wplab.com regarding helping with future updates to the plugin; I think that what you said you want to add makes a lot of sense. :)
