I like where this is going, to design your bento box visually, before having to write code. But it is missing some important polish and a couple more features. Polish wise, drag and drop doesn't seem to work as expected and resizing is a chore. And feature wise I really need to understand how the layout will act responsively and support it. As an aside, not everyone uses Tailwind, giving an option to use plain-old-style attributes would go a long way. Keep at it :D
