please add for the "Advanced View Site" feature of your tool also Hikashop products. so that it is possible on the "add product page" jump after the product is saved to the product like it is possible with the nativ joomla articles.
The way HikaShop handles urls and stores the information in the database, makes it very difficult for adding support for it in Better Preview.
It would pretty much require a rewrite of Better Preview.
There are currently no plans to do that.
