Request / Enhancement for save setting

Hi @jwagner,
Thanks for your works which is very cool.
Just a request here: Why doesn't offer possibility to save stuff in a txt file with "file path,pitch,start..." in it and with a "special playitslowly extension".
This can be pretty cool to reopen the audio file without to re-do the settings.
I'm not a python devel but i suppose it must be simple save the text settings. I hope you'll do.
And yet, thank you very much.

Start by locating the controls or entry points for audio-file selection, pitch, and playback position. Check how the application currently reopens audio and where these settings are held, then determine a suitable saved-settings format and reload flow. Done means users can save the listed settings and restore them for an audio file.
