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

まず、既存の「Show Node Power」エントリポイントとその計算経路を特定し、同じ build に対する計算を繰り返した場合の測定を行います。キャッシュされた結果を無効化する方法と、手動で再計算する方法を定義します。変更されていない計算を繰り返した場合はキャッシュされた結果を再利用し、build に大きな変更があった場合は更新された node-power 値を生成できれば完了です。
