08048a00  int32_t edx  // comment

When marking up functions, I like to add a lot of comments and focus on those. It'd be nice if I could specify a minimum comment indentation, to pull comments out of the noise.

08048a00  int32_t edx                                   // comment

Also, it'd be nice if comments were colored differently than string references.
