Need some flexibility to customize to be able to use this great library

[Subhajit1999]

I found this library great. However there some gaps that I have found. This will be greater if you please solve these issues to make this library more dynamic.

1. Text color, background color, radio button, and icon color change feature
2. Customization of layout width and height
3. Use of the custom font

That's it, I think.
