improvements to audiobook maker

[CtrlAltDefeat55]

I have a few suggestions that might improve your audiobook maker:

Better Error Handling and Visual Feedback

When using the “Regenerate Chosen Sentence” feature, it would be helpful if the newly generated sentence was automatically selected afterward.
Please add a simple status indicator too, such as a green light when a line is fully generated and a red light while it’s still processing. This would prevent accidental overlaps in generation. For instance, I didn’t realize a line hadn’t finished generating and tried to start another line. This caused the tool to crash and prevented me from uploading my project because one audio file was missing or corrupt.
Persistent Settings

It would be convenient if the tool saved settings between sessions. Perhaps you could store these in a JSON file in the root directory, so every time I reopen the program, my preferred options are already set.
Multiple Line Playback

Adding a button to select and play multiple selected lines at to see how it would sound if a line was missing or ordered differently would be much more user-friendly than having to select one line and then choose “play all from selected.”
Improved Controls for Settings

Rather than only allowing users to scroll through values, please enable direct input for settings. For example, typing “8.1” directly for the output speed is more accurate, especially if settings aren't saved automatically.
Thank you for considering these improvements. I hope they come across as constructive suggestions rather than complaints.

I'll take a look at some of these and arrange them on my bugs and features list!
