Interaction with the diagram is buggy (zoom, selection, navigation)

[Janaka-Steph]

Using the trackpad of my Mac, the zoom is reversed, not taking into account my preferences.

When selecting an item, I would expect it to be shown at the center of the canvas, which is not the case.

Having the ability to navigate the tree with keyboard arrows would be useful.

this is sort of difficult to do with the react-storm diagram engine, it really bucks under attempts to navigate programmatically.

I'd recommend not spending too much time on it at first (maybe the zooming one is easier to fix if it's just reading a preference).

Appears to be modeately fixed w.r.t. scrolling tested on a recent Mac.

the zoom to area function is still a bit glitchy, will leave open.
