A proposal has been made to add “private whispers” or “private notes” to topics, allowing users to post personal notes that only they can see. codinghorror suggests that sending PMs to oneself, a feature available since 1.6 beta, could serve a similar purpose.
sam mentions that improving whisper support is on the long-term plan, but not scheduled for a specific release. One potential feature, whisper permission groups, which would allow specifying which groups can see whispers, is likely 2 years away.
sam explains that implementing whisper permission groups would be a complex change, requiring significant updates to the permission model and unread count tracking. This would involve renaming columns, making changes to the permission model, and ensuring no performance impact, potentially requiring 2 weeks of work. loginerror expresses interest in this feature.
Since we introduced the “animals database” in our goat farming community, people would like to add “private” messages (aka whispers) in their own topics and use it like personal notes.
Hence this proposal to add a “private whisper” or “private note” for users to post into topics. I love the universal “private note” name.
Anyone would like such a feature? How would you use it?
For notes, people can send PMs to themselves as of 1.6 beta.
Is this also possible to be planned or not really?
Improving whisper support is on our long term plan, but not slotted on to any particular release.
Maybe one day we will support whisper permission groups, but this is probably 2 years out to say the least.
どのグループがウィスパーを表示できるかを指定できると素敵ですね 
これは前回私がこの問題を検討した時よりもさらに複雑な変更になるでしょう。
問題は、ウィスパーが存在する場合でも、トピックリストの「未読数」を正しく維持するコードが多数存在することです。そのため、「スタッフが見られる数」と「非スタッフが見られる数」を追跡するカラムがいくつかあります。
少なくともそれらのすべての名前を変更する必要がありますが、その後、権限モデルなどさらに多くの変更が必要になります。これは非常に大規模な変更であり、現在のパフォーマンスへの影響を超えずに正しく動作させるには、おそらく2週間程度の作業が必要になるでしょう。
