Abstract: Techniques to control arrangement of items in a user interface is described. In one or more implementations, intuitive rearrangement of items in a user interface is caused by a computing device. A priority ordering of items, one to another, is determined that is specified for display of the items in a first layout in a user interface of the computing device. The items are assigned into respective ones of a plurality of groups that together compose one or more linear arrangements of the groups. Arrangement of the items is controlled by the computing device for display in a second layout in the user interface that is different from the first layout by an amount of display area available in the user interface along one or more dimensions.

Abstract: Technologies are described for resuming activities using activity data collected by an operating system. An operating system provides an application programming interface (“API”) through which applications can submit activity data. The activity data identifies an application and an activity previously performed using the application. The activity data can be presented to users in a UI that includes UI controls corresponding to the reported activities. The UI controls can identify the activity and the application used to perform the activity. The UI controls can be presented in an order determined based upon the time at which the corresponding activity was performed. The UI controls can be selected to resume the corresponding activity. Functionality can also be provided for scrolling through the UI controls, searching the activity data, filtering the represented activities, deleting the activity data corresponding to an activity, and performing other functions.

Abstract: Techniques for a contextual new tab experience in a heterogeneous tab environment are described. In at least some implementations, relevant content associated with a user's current task is determined based on contextual information collected from tabs presented in a heterogeneous tab environment. According to various implementations, a new tab is launched displaying the relevant content in the heterogeneous tab environment. Thus, contextually relevant content can be determined from a current task and displayed in a single location via a heterogeneous tab environment.
