Glad it was helpful feedback. Seems like a noise tool for somebody who wants a quick noise effect, maybe without the ability to afford the full cost for something like Photoshop.
If you're looking for stuff to add that might cool or add distinctiveness:
- Noise Types: Looks like you're using White Noise, or possibly a 2D slice through 3D Perlin Noise. Adding the possibility for other noise types. 2D, 3D (2D slice), 4D (?, 2D slice) of Gradient/Perlin Noise [1][2][3][4], Simplex Noise [5], or Wavelet Noise [6][7] you can select between for the underlying noise function.

- Fractal Brownian Motion Noise (basically, layered factor of 2 noise functions of another type at 1/2 intensities) [8][9][10][11] (Inigo Quilez's article is dramatically easier to read and comprehend than most articles, the WP article is super math heavy and nearly pointless unless you're a math major.)

- Domain warping noise (noise that performs a distortion on the location where the noise is applied). [12][13] This time, the Inigo Quilez article is rather intimidating. However, it can also be used to make much simpler variations like glass ripple distortions, water droplets, waves, ect...

- Noise Colors (White noise, Pink noise, Brownian noise, Blue noise, Violet noise, Grey noise, Velvet noise, Green noise, Thermal Blackbody noise)[14][15][16][17]
