in "public\media\svg\shapes" there are several SVG files that are 350kb+ in sizes. I've checked them and they are PNG-encoded images just put in SVG format, which is outright fake thing. Please, do them in correct SVG's (so those images will be around several KB in size).
@sean please do any update. ALSO, please optimize all images (with using software like "PNGoo" or "Riot") before adding to repo, because the simple images are 200-300kbs, while their compressed (almost loseless around 95+%, without any visual notice) are just 30kb or around, so, your BESTSELLER theme is not optimized well. Take someone to handle this issue..
