Systems and methods are provided for tracing parameters indicative of performance of a mobile device that is not tethered to a host computer. The mobile device is instructed to monitor a performance characteristic when the mobile device is not tethered to the host computer. The instructions may be to trace the characteristic at a certain point, for a span in the future, under certain conditions, or at all times. When the mobile device is later tethered to the host computer, the traced parameter data is transferred to the host computer. Applications that decrease performance, as indicated by the traced parameters, may be debugged or optimized. The behavior of the mobile device before, during, and after tethering to the host computer or to a second device may be observed. The performance of a plurality of untethered mobile devices may also be traced, transferred, and compared.

Improved techniques for automatic (or dynamic) updating (or maintaining) of file groups in a developer environment that stores and executes files are disclosed. The automatic update to file groups can occur when additional files are added to or removed from the developer environment. The automatic update to file groups can also occur when previously stored files are otherwise altered.
