Option to customize the display bubbles of contacts on the job.
Specifically the option to change the colors of the bubble to more colors than just green or greyed-out.
Also the option to add critical notes or the standing of the customer. Some customers we just never want to work with ever again, and it'd be nice to have a way to clearly label that without having it in the display name (which can show up in other places such as estimates/emails/etc).
