This is a Sketch plugin for hiding/showing annotations on a functional specifications document.
It's useful when you use a same Sketch document for exporting:
- Images – with annotations
- Prototypes – without annotations
The Hide and Show commands control the visibility of all layer groups named "Annotations". They impact annotations on all pages and artboards of the open document.
Put your annotations in groups named "Annotations". You can create these groups manually, or use the command Create 'Annotations' group from selection.
1. Download the latest version of the plugin 
2. Unzip the file.
3. Double-click the annotations.sketchplugin file to install the plugin.
That's it! You should see the Annotations plugin in "Plugins > Manage Plugins...".
Sketch will notify you when a new version is available.
