Developing new themes

[i-ky]

I am developing a theme to colorize Zabbix log files. What would be the best way to do it? Would you like me to create a pull request with this new theme (in this case I will proceed with development in a fork of your repository) or do you prefer keeping custom themes for not-that-commonly-used applications out of the mainstream repository (in which case I will create my own theme-only repository like dabrady/colout-themes and cym13/colout-templates)?
