Allow adding class to shapes

I would like to be able to assign specific behaviour to shapes. For example making specific shapes editbale. I know there's an editable field in shapes[] but that is a bit clunky (the user has to select the shape and then move it which doesn't always work very well).

I would like to be able assign a class name to shapes such that I can set specific css properties per shape. Is there a reason why a class/id can't be assigned to shapes? Could this be something that could be added?

まず、shapes[] がどのようにレンダリングされるか、また既存の編集可能なフィールドが図形とのインタラクションにどのような影響を与えるかを追跡します。各図形に対して想定される class/id の動作と CSS の適用範囲を定義し、その後、図形固有のスタイル設定と編集が、既存の図形の動作を壊さずに機能することを確認します。
