What visual indication shows that notes are being sorted by Note Time?

The visual indication that shows notes are being sorted by Note Time is the appearance of a little triangle in the column header for Note Time. This is a common user interface design feature that indicates the current sort order of data within a column. When sorting is applied, the triangle typically points upward or downward, revealing whether the notes are sorted in ascending or descending order.

This functionality enhances user experience by providing a clear and immediate visual cue, allowing users to understand how the data is organized without needing to check each note individually. The presence of this triangle is a widely recognized convention in many software applications, making it easy for users to interpret the sort status at a glance.
