Summary:
The Dom events for the divs that are very close together were not firing correctly causing the old implementation to not track the hovered node correctly. This was really frustrating trying to select a node amongst many close neighbours.
The new approach uses the mouse x,y position and performs a hit test. Currently we do a dfs looking for the first deepest child that interests the mouse x,y. In a future diff we will extract a list when there are multiple candidates.
Hovered node was removed from react props since both the tree and visualisor depend on it meaning when hover state changes the whole app is rerendered. Instead we have moved hover state to an atom which is subscribed to by each visualsation node. Only if the old or new value matches the particular nodes id do we set state. The viz nodes were memo'd to prevent children renderning. The result is that for a hover change at most 2 nodes out of the 500 or so will rerender.
I attempted to do the same with the tree but it wasnt working with the controlled tree environment + focus state. The perf seems fine as is so will leave it for now

Summary:
Upgraded from ant tree library to the much more capable React complex tree. Added the following:
1. Ability to expand / collapse nodes while automatically expanding / collapsing active/inactive children when they change
2. Keyboard controls of tree all the time
3. Basic search functionality
4. Selecting node in tree focuses and scrolls in the tree
5. Hover state for tree

Summary:
Replace draft inspectors with read-only components.
This is a first step into having a richer UI. At the moment, these are read-only components but will likely be extended in the future as to allow editing of values.

Summary: Added scheduler to scan the Native UI every 500 ms to test, Also added instrumentation in a separate event with the timings of each stage visualised in a Data table on desktop which can be accessed with ctrl+I. Currently this instrumentation event is sent every time but it could be a config option controlled from the desktop in the future

Summary:
Scaffolded desktop UI for UI debugger
I changed getroot from an rpc call to an event sent on connect. The root should never change as its the application object.
