It is recommended to add support for Allman-style code snippets.

I noticed that many code snippets in the friendly section use the `K&R` style, which might not appeal to those who prefer the `Allman` style.
I suggest adding more Allman-style code snippets, or providing a way for users to easily swap between styles.
I mainly work with `C/C++` and would appreciate more Allman-style options. Thank you!
