SALT is a great theme,, very good components and features. The responsive theme as well as the Revolution Slider is a hit. Some pro-active support is required from Customer Service as replies tend to be late and sometimes unhelpful.
Looks good, and works fairly well, but a few major issues:
1. Performance is poor, check the demo on Google PageSpeed insights: https://developers.google.com/speed/pagespeed/insights/?url=http%3A%2F%2Fdemo.themesease.com%2Fsalt-multi-purpose%2F&tab=desktop (70/100 for mobile and 45/100 for desktop).
2. Search is poorly implemented, inflexible (only a single way of implementing it in nav), and disappears on mobile (!). This might be non issue for a small, portfolio type site, but for a blog or other site with a lot of content, a poorly done search is a full stop. I find it totally bizarre that on mobile search is set disappear, making it totally unusable for mobile users.
