Naming Items in the Layers Panel
Back in the day, before a laptop became my main work machine, I used to put sticky notes around my monitor as reminders to do certain things in the files I worked on. Those days are long gone, but there are plenty of ways to add notes and labels to content in your InDesign files.
One way is to use the Layers panel.
To add a custom name to a layer, group, or object, do a slow double-click on it (click, pause, and click again), then type the name you want.
So instead of generic names.
You can have something like this.
Just remember that the Layers panel only shows items on the spread you’re currently viewing. And to remove a custom name in the layers panel, select and delete it, then click away from the Layers panel.
