Enhanced timelines in application development environments

A computer-implemented method, comprising:

• accessing code of an application stored in a memory, the code defining a plurality of media components of the application and at least one scripting action;
• providing, by a processor, output to generate a design view in a graphical user interface, the design view comprising a timeline view of activity that occurs over time during execution of the application, wherein the timeline view comprises a plurality of cells and a plurality of tracks, each track providing a temporal view of a respective media component by populating a plurality of cells extending in a first direction in the timeline view, wherein the tracks are adjacent in a second direction in the timeline view so that cells adjacent in the second direction correspond to activity that occurs at the same time;
• populating the timeline view with at least one additional track, the at least one additional track comprising a scripting track comprising an action element representing a portion of scripting code defining a series of discrete operations to be performed at a particular time or keyframe by the application, the particular time or keyframe identified by a position of the action element on the timeline, wherein the at least one additional track comprises a label track including a label associated with the keyframe of the timeline;
• and
• receiving a selection of a cell of the timeline to define or edit the label to be associated with a selected keyframe of the timeline, wherein the label is used by the scripting code.

A computer program product comprising a non-transitory computer readable medium embodying program code, the program code comprising:

• program code for providing a graphical user interface of an application development environment;
• program code for providing, in the graphical user interface, a timeline view that includes activity that occurs over time during execution of an application under development, wherein the timeline view comprises a plurality of cells and a plurality of tracks, each track providing a temporal view of a respective media element by populating a plurality of cells extending in a first direction in the timeline view, wherein the tracks are adjacent in a second direction in the timeline view so that cells adjacent in the second direction correspond to activity that occurs at the same time;
• program code for providing, in the timeline view, a default configuration of the plurality of tracks, the default configuration comprising at least one track corresponding to a media element of the application under development, a label track, and a scripting track, the scripting track comprising a visual representation of a scripting element representing a portion of scripting code defining a series of discrete operations to be performed at a particular time or keyframe by the application, the particular time or keyframe identified by a position of the action element on the timeline, the label track including a label associated with the keyframe of the timeline;
• and
• program code for receiving a selection of a cell of the timeline to define or edit the label to be associated with a selected keyframe of the timeline, wherein the label is used by the scripting code.
