Please make the member list with contact info available on iOS and Android devices. Teams may not have all contacts loaded into their device's contact list so being able to see people on the project, their role, email, and phone would be very helpful.
Also, allow for users to tap on a someone's name when viewing an item (such as an RFI) would bring up that person's contact card. From there they could tap on an email or phone number to get in touch with that person.
