Definitely a good app. Works better than the other Dynamic Notifications application which never worked on my phone. The app however always refers me to Accessibility Settings to enable Active Notify even when it already is enabled. Also, the application has trouble persisting and working. Sometimes it just stops working and will not start up again until a reboot.
On design side, I would like to be able to add shortcuts or change the size of the shortcut icons since they are really big. Otherwise great app! Definitely very useful. Looking forward to more improvements.
