It's not unusual to accumulate so many notes that it becomes a challenge track the notes that are most important. To make it easier to keep track of those notes, you can add them to your Favorites. Even if you don’t have that many notes, this can be a very efficient method for locating and access information as quickly as possible.
Nimbus Note has a dedicated section for Favorites, which helps you readily distinguish the important notes from all of the others. Also, you can sort your Favorites. For example, you can sort your Favorites by date, color, reminders, or any other designation.
