Is your feature request related to a problem?

It's frustrating to have to deal with each one of these manually

Describe the solution you'd like

It would be nice if POB had standard multiselect functionality.

Standard OS-level functionality would be nice: click and hold Shift to select consecutive items, and hold down Control to select individual items.

Describe alternatives you've considered

n/a

Additional context

If you wanted to get fancier, you could experiment with a Gmail-style checkbox UI and have a star/favorite functionality, but I think that is more than what people would want, and I assume it would take longer to implement.

この issue ではファイルやテストが指定されていないため、まず Lua アプリケーション内でビルド選択画面と、その入力処理のエントリーポイントを見つけます。選択状態がどのように表現されているかを確認し、その後、Windows で Shift によって連続する項目を、Control によって個別の項目を選択できることを確認します。
