Use as outliner/tree structure like Logseq

[yngwi]

Hi, I wonder if it is possible to modify editor.js to work as an outliner like Logseq. This means not only have blocks below each other but to structure blocks in a tree-structure where blocks can have siblings (like it is now) and children (with increasing indentation for each level). I wonder mostly about the built-in drag-and-drop functionality, the position can be stored in the block data itself without to much trouble, I guess. How easy/hard would it be to modify that you cannot only move blocks up and down but also "left" and "right"?
