I absolutely hate this app too. I also hate that a very simple to the point flash light requires a 2x1 widget. Practically everything I use on this phone is alternatives to Samsung apps.
Alarm clock plus is free and highly regarded, whatever the same annoyance as you with this app. Ideally I want one like on my old HTC phone where I can tap the digital clock on my home screen and it takes me to an alarm page aswell as other useful features like countdown and stopwatch but I haven't found anything like that yet. Seems stupid having unnecessary icons on the screen when one should be able to cover a host of them.
