Add "Reply" Functionality to Notes

It would be helpful to add the ability to "Reply" to individual notes. For example, if I add a note and @mention someone, they should be able to directly reply to that specific note, creating a mini-thread within the original note.

This would:

• Keep related conversations grouped together in context
• Reduce clutter on the Activity screen
• Improve productivity by making it easier to follow discussions

This threaded approach would provide a cleaner, more organized experience—especially in collaborative environments where multiple notes and mentions can quickly become overwhelming.
