Since firmware 1.4 AudioMoth writes a CONFIG.TXT file when the switch is set to Custom mode. Although the creation date-time of the file tells it, wouldn't it be useful to have a timestamp recorded _in_ the file itself ? It would then appear in a print or a screen snapshot. Currently that CONFIG.TXT file is overwritten each time the switch goes to Custom, thus loosing previous configuration info. Could new infos be appended to an existing file instead of creating a new one ? Or would be nice to have mutiple config files named date_time.txt or date_time.log That would make the file appear on top of the .wav files chunk in a directory listing. And a last suggestion: what about ending end each line with CrLf (Hex 0D 0A) instead of Lf (Hex 0A) alone. Basic editors like Windows Notepad would better display file contents. Just some thoughts... Thank you all the team for this marvelous little thing that you brought to all of us. Pierre
