Intelligent user interfaces for multiple communication lines

A system comprising:

• one or more processors;
• memory storing one or more user interface paradigm preferences operable to indicate a communication-line-separated user interface paradigm or a communication-line-aggregated user interface paradigm;
• a user interface paradigm selection engine operable to receive the stored user interface paradigm preferences and a user interface type being displayed and output a chosen user interface paradigm based on user interface paradigm selection rules, wherein the user interface paradigm selection engine supports a communication-line-separated user interface paradigm and a communication-line-aggregated user interface paradigm;
• and
• a display operable to present a user interface according to the chosen user interface paradigm;
• wherein the system is configured to:
• receive user input via the user interface presented according to the chosen user interface paradigm;
• and
• responsive to the user input, navigate to another user interface or perform one or more communications actions.

One or more computer-readable memories, magnetic storage devices, or optical storage devices comprising computer-executable instructions for performing a method comprising:

• presenting a home user interface comprising a first activatable user interface element configured to initiate messaging via a first communication line and a second activatable user interface element configured to initiate messaging via a second communication line;
• receiving activation of the first activatable user interface element;
• responsive to receiving activation of the first activatable user interface element, showing a conversation list user interface for the first communication line, wherein the conversation list user interface implements a communication-line-separated user interface paradigm;
• receiving activation of a particular conversation out of conversations presented as part of the conversation list user interface;
• and
• responsive to activation of the particular conversation, presenting a conversation user interface comprising a message of the first communication line and a message of the second communication line, thereby implementing a communication-line-aggregated user interface paradigm.
