Re: X-Cart reBOOT (reDUX) Template
reBOOT uses Flickity for carousels (used to be Swiper in old version), if you want to disable prev/next arrows it's fairly easy to do, just a JS setting.
At the moment you can choose from 3 product layouts, but you can't do it on a per-product basis yet. You can however set the sidebar on a per-product basis.
For category pages, you can set the sidebar on a per-category basis. You can also display subcategories as icons or lists, as per usual. There's also second descriptions for categories.
