First of all, this is NOT MY app.
I would like to thank the author of this app!

Seems like the author didn't make an announcement thread, so here is a thread about this wonderful settings app!

With this app you can:

• Lock the home screen orientation to portrait or landscape, or unlock it to have it both ways.
• Hide weather icon
• Change all the text on the home screen to white for better reading
• Use wallpaper on home screen (you can even change the blur and brightness of the wallpaper)
• Use wave live wallpaper à la PS3/PSP background (You can pick a color scheme: Black and white, cyan or magenta)
