I'll do that later but I don't think it will lead to extreme CPU consumption. There are many ways to improve performances of idle/almost idle ui. Caching can be useful for large blocks of text as it tend to be the slowest thing to render. But it is preferable to incrementally optimize/add complexity and check assumptions and not make large architectural decisions ahead of time. One way to reason about it is to think in terms of pure data transformations.
