The current version doesn't work, but I'm trying. In fact, the format of notion's underlying JSON block is completely different from the principle of obsidian's markdown implementation, and it is difficult to elegantly implement multi-column layout in markdown text. I am thinking of making a new plugin or a pure CSS approach to implement the multi-column layout function with dragger. If it is too complicated or the result is not ideal, this feature may be abandoned.
My current idea is to flag a multi-column area by embedding an identifier. However, some degree of Marker Intrusion is inevitable in order to achieve this functionality.
