Abstract: Implementations relate to relate to interface elements for directed display of content data items. In some implementations, a method includes causing a subset of content elements to be presented in a display view of a graphical user interface on a device, the set of content elements corresponding to a collection of content data items. Search topics are identified based on one or more content characteristics associated with content elements that are within a threshold distance of the subset of content elements in the display view. Topic elements are displayed in the interface, corresponding to the search topics. In response to a selection of a particular topic element based on user input, the collection of content data items is searched to identify resulting content data items that have content characteristics corresponding to the selected search topic. The display view is updated to present resulting content elements.

Abstract: Implementations generally relate to storing content items. In some implementations, a method includes receiving content items on a mobile device. The method includes storing the content items on local storage on the mobile device. The method includes determining available local storage capacity of the mobile device. The method includes uploading content items to secondary storage, and selecting content items to remove from the local storage or add to the local storage based on predetermined criteria, for example, when the available local storage capacity meets a threshold available local storage capacity.
