Yes. WP Lister Pro extends the schema with additional columns for variations, multi-account, and Best Offer settings, and SleekView surfaces any new column automatically when you re-scan the table. The same inline edit and preset features work; you just have more fields available to filter and sort against.

Yes. SleekView writes through WP Lister's documented update functions rather than touching the eBay API directly, so the same revise call WP Lister would send from its default UI fires from your edit. That preserves rate limiting, error handling, and any WP Lister cron logic that batches calls during quiet hours.

Yes. You can run a separate orders table reading wp_ebay_orders, or join key fields like item_id and buyer into the listings table. The second pattern gives a single grid where a row shows a listing with its last order, last error, and current eBay status, which is the right shape for support queries.

Yes. The Amazon plugin from the same vendor uses a similar schema with wp_amazon_listings and wp_amazon_orders, and you can configure SleekView the same way you configured the eBay tables. Some columns differ, like Amazon ASIN versus eBay item ID, but the workflow patterns are identical.

No. Server-side pagination, indexed lookups on item_id and status, and on-demand column rendering keep the table fast even with tens of thousands of listings. The default WP Lister UI tries to render everything client-side past a certain page size, which is the source of the slowness many cross-listers feel at scale.

Yes. Multi-account WP Lister setups expose an account ID column, and you can filter on it. Each account becomes a separate preset, so a store manager logs into the table and sees only the marketplace and account they own. eBay UK and eBay US setups can run side by side without confusion.

Yes. Item Specifics required is the most common ended-listing error in apparel, electronics, and parts categories. Filter Last Error to that string, group by category, and bulk update profiles or template fields. One fix template applied to fifty rows clears a queue that would take hours through the default per-listing edit flow.

Yes. Any filtered view exports with its visible columns and current sort. A weekly export of orders by month, joined with profile and category, drops cleanly into a spreadsheet for finance reconciliation. eBay's own report tools are limited; a CSV of your local data with full WooCommerce context is usually more useful.
