Happy to help 🙂
Regarding the “… starting at…” question – I believe you can already do that. Please try adding this:
Starting at [alg_wc_product_ppq_data field="price" level_num="last" product_id="%product_id%"]
to either “Discount Pricing Table > Shop page” or “Replace Price > Shop page” (both options are in “WooCommerce > Settings > Product Price by Quantity > Info”).
Please give it a try and let me know what you think.
P.S. And if you like the plugin, please consider leaving me a rating here or here.
