	At an even higher level, the user was significantly influenced by the resources provided for his use. His vocalizations and use of operating system functionality (particularly OS X's Expose) indicated mental clustering of the above subtasks into higher tasks associated by resource. It is meaningful to note that these higher-level tasks were approached in parallel—the user would often abandon an image subtask and return to it in a later subtask.

			* User would click the opacity tool twice every time, which tells me he didn't initially think that his first click had "worked"—efficiency in response is important
			* User would perform "visibility" operations, like expose or the layer eye, while thinking, perhaps so he could keep his mental image of all the program elements as fresh as possible
			* User selects tools that are already selected, especially in moments of peak frustration, and repeatedly tries operations that have no effect
			* User liked Expose, though he had never used it before (Windows user)
			* User was able to integrate Expose into common series of operations, such as select all/copy/select separate image/paste, which he was able to perform very quickly

	We examine workflow from participants given an open-ended image manipulation task. Given one high-level creative task, the user was responsible for deciding the lower-level tasks necessarily to complete it (and was given the resources for several possible decisions, in the interest of time), deciding the operations necessary to complete those tasks, and discovering the interactions necessary to complete these operations (with basic terminology provided, again, in the interest of limited time).

			User had intermediate experience with Photoshop—knew concepts and capabilities, if not specific terminology (which was provided to the user, when asked) and functions (which the user needed to discover on his own).
