Version 3.64.25 allows gauges to be added offline. However, you must be connected to allow the program to populate the supported PIDS . Then you may disconnect and add gauges for later use.
PIDS will be cleared on new connection, app exit and screen rotation. I will make more improvements with the offline in future release. There may be a conflict by loading invalid Gauges Profile type with the current PID list.
I have not tested it thoroughly and if problem exist please report.
