That makes it easier, for sure, thanks!
I'm going to play more with it later.
BTW I was curious about the new TTS developments and found that in the latest available preview there's something not working correctly when changing voices. Also, I was asked to restart the PC (Windows OS), but I'm pretty sure I had all Calibre stuff (editor, viewer) already closed before installing. But I may be wrong about this.
The TTS issue is that I have to re-open the book to have the voice change to another one.
Oh, and I forgot to thank you for the pause after sentence setting. It's a very interesting addition.
