Feature Request: specify agent color in config #1973

Been loving the tool this far. Thanks @thdxr and team for this awesome tool.

This helps to find the primary agent with a better UX and better muscle memory, in a way this can allow users to organize their agents visually and find them easier.

Another small thing would be the ability to order the primary agents, don't know if they follow recency or definition order on the agents folder, but would be a nice add-on!

Thanks for the awesome work!
