Shogun ‑ Landing Page Builder

This app is great and has lovely customer service (I asked a question and they emailed me back with detailed answers within the hour). However, I wish the design-by-device-type was set up differently -- it often feels like a maze to adjust margins and paddings per device, with the tool sending you back to a sort of 'start menu' when moving between device settings! It would be great if this tool allowed a view which would only show options for a device type at a time (with no possibility to change the other device settings), to allow for further customisation. Currently, pages on mobile or tablet still look clunky if you have elements in 2+ columns. There are also some header bugs for mobile design. Otherwise, it's a great tool, for those willing to figure it out!
