All annotations added to your screen are listed under the Annotations tab on the right panel with their types. If you'd like to only look at certain types of annotations, you can easily filter them from the right panel. This will also filter the annotations on the screen.
When you click on an annotation from the right panel, it directly opens on the screen to point where exactly it's added to.
☝️ Zeplin sorts the annotations on the right panel based on how they're sorted on the screen. If you move an existing annotation below/above another one, their order will change on the right panel too.
Every annotation has a unique link to share with your teammates. You can right-click on an annotation and copy the Web link or App URl.
