Arranging user representations according to a priority of users that are concurrently generating instant message content

A computer-implemented method, comprising:

• receiving, at a first client device, instant messaging (IM) data associated with an IM session that is being hosted with respect to a plurality of user accounts, the plurality of user accounts including at least:
• a first user account associated with a first user representation,
• a second user account associated with a second user representation, and
• a third user account associated with a third user representation;
• causing, based on the IM data, a display of the first client device to render a first graphical user interface (GUI) corresponding to the first user account;
• receiving, at the first client device, an indication that first message content is being generated at a second client device through a second GUI corresponding to the second user account concurrently with second message content being generated at a third client device through a third GUI corresponding to the third user account;
• and
• causing, based at least in part on the indication, the display to modify the first GUI to simultaneously render both the second user representation and the third user representation in association with at least one typing activity indicator.

A system, comprising:

• one or more processing units;
• and
• a computer-readable medium having encoded thereon computer-executable instructions to cause the one or more processing units to:
• communicate instant messaging (IM) data associated with an IM session between a plurality of client devices;
• receive, from a first subset of the plurality of client devices, a plurality of user input signals, wherein individual user input signals of the plurality of user input signals are initially received at a plurality of different times;
• determine, based at least in part on the plurality of different times, at least one priority between at least a particular user input signal, of the plurality of user input signals, and other user input signals of the plurality of user input signals;
• determine a graphical arrangement associated with displaying a plurality of user representations corresponding to the plurality of user input signals, wherein the graphical arrangement is based at least in part on a size of the first subset;
• and
• cause, based at least in part on the at least one priority, a second subset of the plurality of devices to display the plurality of user representations in the graphical arrangement.
