I found the log summary. That does the trick

The question is, why? Why do you want to return to the list of logs?

If your answer is because you wish to go through many logs in turn, extracting information from them, use the Log Summary tool. It is intended for that purpose.

These days I was reviewing a bunch of several flight to copy data to the aircraft's log and to our club-intern flight log.
On my iPad  I first choose "Logs" and find myself on a page with all logged flight; then I choose the flight needed and get another Screen.
That is correct.
But in this Screen I can tap Close and find myself back on the main Screen. Wouldn't it be more logic to return to the list of flights instead of returning to the main Screen ? In my eyes - yes; stay on the list of flights.
