You can install the plugin from Sketch Runner, Sketchpacks, and Sketch Toolbox.
Download Sketch Dockpreview and double-click to install.
Press ⇧⌘D (Shift + Command + D) to preview the current active artboard in the dock.
To restore the icon back to the default Sketch icon, go to Plugins > Restore Sketch icon. If you quit Sketch, the icon will automatically restore by itself.
If you'd like to change the shortcuts, you can change the manifest.json file in Dockpreview.sketchplugin/Contents/Sketch and change the shortcut to your liking.
Note: When the plugin updates, this will overwrite the
manifest.jsonbecause of versioning.
