Abstract: A user interface configuration system, according to various embodiments, is configured to provide a centralized interface containing a plurality of user-defined content in the form of content blocks. In various embodiments, the system is configured to automatically access particular content blocks according to one or more time constraints. For example, the user interface configuration system may enable a user to configure a day's worth of lessons in the form of individual content blocks. In particular embodiments, each individual content block may include a set of content (i.e., documents, applications, links, videos, images, etc.) that must be accessible during presentation of the content block. Such an arrangement reduces cumbersome, time-consuming processes for navigating to different pieces of content stored on, or otherwise accessible from different locations that requires the use of arbitrary commands to access by providing a single interface defined by required content and time constraints.
