在子任务中，回车无法实现换行（因为回车是第二个子任务的创建，这可以理解也很合理）
但，其实 option+回车，是可以在子任务中实现换行操作的，但是！编辑完了以后，实现换行的那些文字，全部自动转移到备注里了。
希望可以修复这个问题，并且给备注和子任务一些Html 的权限，比如 cmd+shit+h 是高亮文本等操作，从而增加区分度，而这个高亮文本的颜色，可以设置为单一的颜色即可，并且可以在主题设置中编辑。这样就非常完美了～
至于子任务中的换行，我认为可以shit+回车，或者 option+回车，真正实现子任务换行的操作，而不是目前的bug。
In subtasks, a carriage return does not enable a line feed (since the carriage return is the creation of the second subtask, which is understandable and reasonable)
But, in fact, option + enter, can be realized in the sub-task line operation, but! After editing, the realization of line breaks in the text, all automatically transferred to the note.
---I hope to fix this problem, and give notes and subtasks some Html permissions, such as cmd+shit+h is to highlight the text and other operations, so as to increase the differentiation, and the color of the highlighted text, can be set to a single color can be set, and can be edited in the theme settings. this will be very perfect ~ ~!
As for line breaks in subtasks, I think you can shit+return, or option+return, to actually make subtask line breaks work, rather than the current bug.
