FEATURE/FUNCTIONALITY/MECHANISM	THEORY CONCEPTS	CODES AND BEHAVIOR FACILITATED	RELATIONSHIP TO DIAGNOSTIC AND CARE PROCESSES
Gather and spatially arrange any information elements from the EHR together on the same page, by click and drag.	DC, K, IS, CL, E	Identify information sources; arrange display elements to support procedure and prioritization, juxtaposition, data examination, exploration, explanation, hypothesis evaluation, discrepancy processing, metareasoning and summarization; assign regions for particular purposes.	Make relationships between variables, order according to diagnostic or treatment importance or relevance, communicate significance to self or colleagues, assist thinking, store data
Make and share custom lab panels from any user-selected labs. Likewise, share user-created tabs (page interfaces) containing collections of notes, lab panels, plots, RSS feeds, etc. Creators of shared elements are identified in the list for importing elements, so users may choose based on their informal knowledge of the authors’ specialty, expertise level, etc.	DC, P	Create display more exactly fitted to patient case or general needs; share this with colleagues; facilitate data examination, exploration, and discrepancy processing.	Display all elements of a patient case on one screen, facilitating thinking and decision-making without the need to navigate, thus speeding the process.
Set a tab containing user-gathered elements as a template so that labs in the page are automatically updated with new information as it becomes available.	P, communication, & collaboration	Automatic information updates, standardization.	Facilitate rapid and up-to-date case review in subsequent sessions; standardize process across sessions, patients, and clinicians; and communicate with colleagues.
Create multiaxis plots of any desired types of lab test values together on the same plot (a mashup) encompassing all available patient data; pan, and zoom from a years- long scale to minutes/seconds.		Data examination, exploration and summarization, discrepancy processing.	Facilitate decision-making
Collapse and expand widgets; edit header colors and titles; view widgets full screen.	IS (marking, grouping, perception, choice, etc.)	Data identification, examination, exploration, marking, grouping according to topic or relevance, increasing perceptibility, summarization, data storage.	Facilitate reading notes or full-text journal articles; speed case review and decision-making.
Sticky note: A “sticky note” can be added for inserting text into the interface, with a customizable background and header color.		Allows user to write notes or anything else desired in a widget.	Combining user-created text with other information on same screen.
RSS feed widget: Through a multistep process, a user can set up RSS feeds to appear in a widget.		Inclusion of self-updating (therefore current) information (e.g., standing Medline search results) in a widely used format; and drill-down to full text journals in the interface.	Facilitating EBM and guidelines, alerting, etc. Any RSS feed allowed. Inclusion of diverse external information sources.
Mouse over lab results preview: Mousing over the left-hand lab menu link gives a preview of the lab panel.		Allows user to preview widgets before inserting them into the tab, facilitates selection and mitigates the need to take action to remove unwanted widgets.	Decreases unnecessary actions in widget selection and placement; rapid information overview.
