能不能开发一个新功能：复制任务
应用场景：我周五去一次超市，用子任务里有10个物品，买一个勾一个；下一周我还要做一样的事，但是这个重复没有明显的周期性，不是repeat。所以我觉得简单的方法是，我不用敲那么多键盘，复制一下完成了的旧任务，再修改一下即可。
类似的情景还用出差的物品整理清单等。

This would be really useful for many kinds of checklists or "mindsweep checklists" and other "template" lists (perhaps in a Someday project), where you are usually only going to select some, but not all, of all the items.
Could be implemented as a "clone to Today" bulk command in the the right click menu - you first select all the desired tasks using ctrl-click as usual, and then just hit the "clone to Today" command.
