Somewhat buggy, as may require re-installation of Simple suite Apps to ensure app icon colours actually change, as can otherwise stubbornly remain default orange. Also continues to annoyingly allow app nags for upgrade, even when Pro versions are in no way wanted or required. Importantly, be aware that if re-installation of Simple suite apps is required to enable Thank You app functionally to operate, undertaking data export beforehand must take place, as otherwise all app data will be lost!!
