I didn't read through all of your guy's posts here (sorry), but here's what I believe that, if it should be added, would make the Oxwall store more efficient and beneficial to Oxwall-users:
-Version Compatibility: Require an additional statement in the plugin.xml like <versioncomp> to state which version of Oxwall supports (must be the highest version it can support). This will show on a plugin/theme's details.
-Search filters: Let customers filter store results by Plugin/Theme Version, Cost (a slider going from smething like $0 to $300), Rating count; all of this along with the plugin/theme type.
-Update Notification: Update the customers of a plugin/theme on both their Oxwall.org accounts and via email that said plugin/theme has been updated. The email notification can contain the changelog, the on-site notification will take them to the plugin page.
-Changelog: Most developers on here have little to NO changelog for their plugin updates, and they easily get lost in the plugin/theme forums. I think on the plugin edit page, there should be a text area for "CHANGELOG" that the developer can fill out with all the changes, and that the system can read a CHANGELOG.xml file from plugin's sources to automatically fill it in. The change log can be viewed by clicking a "Changelog" link in the last bit of a plugin description.
-Trusted Sellers: A badge for third-party developers/companies that have met certain standards to be trusted from the Oxwall community. For example, to earn the badge you must make say over 500 plugin license sales or have a total of 100 5'star feedbacks from any/all of your items. Users can then sort the store by Trusted Sellers.
-Safety Information: To keep customers protected, on plugin/theme pages there should be listed "Safety Information." This displays when the mod team finds that the plugin/theme uses/relies on other third-party scripts/software to function but they still pass it. This could also include simple things such as "Style collisions may occur" or "Uses an older version of jQuery." This way customers can stay more in-formed.
Last, I'd like to recommend a style update: on a profile page that has oxwall store items, it should display like the 1.7 photos display: pinterest style with the main picture showing and it's details "name, version, etc." available on hover. This makes browsing certain merchant's items easier.
Thanks for your time.
