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.
