Happy to help. I can confirm that v0.5.5 correctly saves the last selected playback state and position (edit: I missed that paused sounds do not save the playback position correctly: https://itch.io/t/5380048/win056-paused-sounds-get-an-invalid-playback-position). Maybe it's negligible since the tool is in early development but I'd like to point out that when opening a pre-v0.5 project the sounds are all set to paused by default and don't start at the correct position.
