Shogun is certainly the go to for page building in Shopify. For the most part everything runs smooth and building basic pages in no problem. I hope to see more compatibility in editing between desktop and mobile in the future (a lot of the desktop preset sections do not convert to mobile). Would be nice to edit one without effecting the other. (without having to constantly toggle screen settings). Also, sometimes the preview page glitches. overall, it def beats the default Shopify page builders the themes are limited to.
Hey Metta! Thank you for the kind words. We chatted over email a bit, let's re-ignite that convo. We have a feature called "Screen Settings" that allows you to edit each version of your page to create a unique design for mobile and desktop separate from each other. We are also working on improving this in our future development, expect even more robust cross screen editing controls soon. What issue are you having with your preview page? We'd be happy to take a closer look for you. If you could reach out to us at email@example.com we'd be more than happy to help. Thanks!
