I see few implementations but wanted to focus on supporting finding vanity addresses that can be run easily like a CLI tool. Features include
1. Finding addresses from a list of words specified.
2. Finding addresses that contain vanity string only in the beginning or only in the end of the address or either.
3. Focus on performance which is in progress by running in parallel based on number of cores in CPU.
