Is your feature request related to a problem?

No but kinda I guess? Its a "problem" that the "show node power" feature demands so much cpu power/time.

Describe the solution you'd like

(I'm not 100% sure if this is implemented in some form)
Add an option to cache previous calculations since you will often be using the same weapons/skills but there will also need to be a button to recalculate the power nodes in case you make big changes to the build.

Describe alternatives you've considered

Add the option to only focus on notables and ignore all small nodes

Comienza localizando el punto de entrada existente “Show Node Power” y su ruta de cálculo; después, mide los cálculos repetidos para el mismo build. Define cómo deben invalidarse los resultados almacenados en caché y cómo funcionaría un recálculo manual. Se considera terminado cuando los cálculos repetidos sin cambios reutilizan los resultados almacenados en caché, mientras que los cambios sustanciales en el build pueden producir valores de node-power actualizados.
