This reminded me, I saw tooltips being a large chunk when I profiled my react app. I should go and check that.

Similarly, adding a modal like this

{isOpen && <Modal isOpen={isOpen} onClose={onClose} />}

instead of

<Modal isOpen={isOpen} onClose={onClose} />

Seems to make the app smoother the more models we had. Rendering the UI (not downloading the code, this is still part of the bundle) only when you need it seems to be a low hanging fruit for optimizing performance.

That breaks the out transition.

You can add some TransitionManager that uses a bool prop whether or not to render its children and when the prop goes from true to false, keeps rendering its children for some amount of time.
