The identifier displayed on the touch-sensitive display is dynamically sized based on the size of the contact area.

Abstract: Methods and apparatus for developing software for a computing device are provided. One method includes accessing input received from an input peripheral, accessing a definition file defining a plurality of tools for code development, providing a development assistance tool on an output peripheral based on conditions and instructions in the definition file that match the input. Another method includes receiving an engine definition file corresponding to a development assistance engine incorporated into the IDE, editing the engine definition file to include programming tools that correspond with the a computer language that is native to the computing device, and saving the edited engine define file for subsequent use by the IDE.
