Abstract: Systems and methods are disclosed herein for caching structural elements of electronic documents. A plurality of indices is stored in a database. The plurality of indices corresponds to locations within an electronic document of portions of a structural element. A mutation to the electronic document is received. Based on the plurality of indices, it is determined that the mutation modifies the structural element. Based on the determination, the structural element is updated. The updated structural element is displayed at a user device.

Abstract: A mobile device that supports a plurality of SIM profiles each corresponding to a different wireless network, measures a current network quality of a first wireless network and obtains network quality information for a second wireless mobile peer device as measured by the mobile peer device. The mobile device switches from the first wireless network to the second wireless network based on the obtained network quality information from the mobile peer device and based on the current network quality of the first wireless network by the mobile device. The network quality measurement received from the mobile peer device is provided through a wireless peer to peer communication link such as a Bluetooth link or other suitable non-internet protocol peer to peer communication link. The mobile peer device also supports a plurality of SIM profiles. Corresponding methods are also described.

Abstract: Systems and methods may include updating subsets of elements of electronic documents. Associations of types of mutations, mutation locations, and subsets to update are stored in a database. A mutation to the element is received, and a type and location of the mutation are determined. Based on a stored association, a subset of the element is determined. The determined subset is associated with the determined type and determined location. The element is updated by updating the subset, and the updated element is displayed on a user device.

Abstract: Systems and methods are disclosed herein for copying inherited properties between electronic documents. An input to copy a source child element from a source application editing a source document is received. The source child element inherits a value of a property from another element. An input to paste the copied element into a destination document edited by destination application is received. The copied element is pasted into the destination document. The destination application retrieves instructions to determine a destination child value of the property and uses the instructions to determine the destination child value. The destination child value is consistent with the value which would have been determined had the copied element been pasted into the source document.
