Lazy loading less crucial routes has led to a marginal 20 kb reduction in the initial JavaScript transfer from the previous 700 kb total. The most substantial enhancement could come from implementing lazy loading for the Question component, potentially saving about 260 kb. However, the current priority is to maintain seamless user access to the core app functions immediately after the initial load, at least until the website becomes accessible as a PWA.

Lazy loading modals from react-modal is also not possible as react-modal advices against conditional rendering modals. Reason seems to be related to createPortal.
