ComfyUI custom node like ReactFlow memo

[kakachiex2]

I was trying to create a fully custom node but the new frontend Litegraph don't let me customize the base node completely it renders everything outside the base node and a lot of glitches, is there a way to create an empty node body and add my own label, card, wire, handle, floating toolbar etc... Any help from the expert.

To solve this for now I create an extension that load my own frontend with vueflow and use ComfyUI backend for processing but I really want to maintain everything inside ComfyUI itself.

Here is a screenshot of the ComfyUI VueFlow workspace in an overlay mode.
