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?

首先跟踪 shapes[] 的渲染方式，以及现有可编辑字段如何影响形状交互。定义每个形状预期的 class/id 行为和 CSS 作用范围，然后验证特定形状的样式和编辑功能能够正常工作，且不会破坏现有的形状行为。
