Feature Request: Add CallSign and Timestamp to Backup Filename + JSON Formatting

[aendes]

Hello,

I have several Trackers and iGates with different configurations and various CallSigns. It would be really helpful to have the ability to download the backup file with a filename that includes the corresponding CallSign and a timestamp for easier organization and identification.

Additionally, it would be great if the downloaded JSON could be formatted in a more readable way, with line breaks and proper indentation (pretty-printed).

Thank you for all your hard work and for continuously improving this project!

Best regards,

Aendes

the callsign add could be done without any problem, the time I guess is redundant as you have this as it is downloaded to the PC.

the pretty printed part I dont know (yet) how to achieve it, but will search for it
