Optimization of tree component

[neyser95]

The rendering of the tree starts to take longer as a user's application begins to grow trying to find a good way to enhance the rendering of the tree would be a great.

wondering if the react devtools global hook gives access to the virtual dom or shadow dom. maybe we can traverse that instead of the actual rendered nodes?

the tree component is too laggy and makes the extension unusable for me.
