In the Android version of Oracle Synopsis you can leverage a great ‘newish’ Android feature called App Shortcuts to access your most important projects quickly.
Just long press on the Synopsis app icon for about a second and menu will appear along with a quick vibration. Release, and simply tap any of the menu options to quickly access a current project or import a new file.

You can also tap and hold on any of the menu ‘handles’ (lines on the right side of the menu item) and drag that specific action anywhere on your launcher.

Notice the Excel looking icon that I am dragging on my launcher in the image above.

Now I can just tap the new icon and open a specific Synopsis project directly!
Please note this feature requires Android 7.1 or above.
