Today users must manually export the My Pokemon list. I would like to propose the option of always exporting the list on stop/exit. Developers have started using the automatically saved logs to build reports and analytics around botting activity. Similar development can be done using the Pokemon list (and are often requested) such as an offline PokeDex, Pokemon analysis, etc. without having to bloat PokeFarmer by building that functionality into it.
Honestly, similar benefit could be gained by leaving the last known information on the screen when the Stop Bot button is pressed instead of clearing it all.
