[ENHANCEMENT] Add custom functions to the app

[KareemMAX]

Is your feature request related to a problem? Please describe. In the current state of the app, I can only set static colors.

Describe the solution you'd like Adding a section for applying different patterns, just like the original Magic Home Pro app.

Describe alternatives you've considered Currently I'm using the app separately to apply those effects.

Additional context By using setPattern function from magic-home, this would be easily done.
