1. Porto does not have a testimonial element with a scroll function for Elementor. Major Drawback.
Although, there are some premade testimonials coded somehow to display scroll.
Please add a testimonial element with a scroll function for Elementor and other builders.
2. Please add ready-made demos websites with all pages as offered by other themes in the market.
3. Many good blocks are available inside Porto theme, but they are coded, which limits their use. All such functions should be added through added proper elements like other functions.
