VariMatrix — Variation Manager for WooCommerce

WooCommerce’s native variations UI paginates at 10 rows and slows to a crawl past 100 variations. VariMatrix replaces that workflow with a fast spreadsheet grid embedded right in the product edit screen:

• Chunked loading + virtual scrolling — 1,000 variations scroll smoothly; only ~30 rows exist in the DOM.
• Inline editing — prices, stock, SKU, status, enabled toggle, featured image, description, weight and dimensions.
• Keyboard driven — arrow keys move between cells, F2 or Enter starts editing, Enter saves, Escape cancels, Tab walks across a row. Like a spreadsheet.
• Choose your columns — show, hide and reorder columns; your layout is remembered.
• Nothing half-saved — edits stage as amber cells; one Save button writes in safe batches of 25 with a progress bar and per-row error reporting.
• Filter and sort any column — pick multiple values per column, combine filters across columns, then bulk edit exactly what is left.
• Bulk actions — set prices, raise or lower by percentage or fixed amount, set stock, enable/disable, generate SKUs from a pattern, delete.
• Fill-down handle — drag a value down a column.
• Zero frontend footprint — no frontend assets, no frontend hooks. Your storefront is untouched, provably.

All writes go through the WooCommerce CRUD layer, so price lookup tables, transients and third-party hooks behave exactly as if you edited variations one by one.
