Describe your suggested feature

When you open a chapter the floating TTS button is at the middle of left side, but if you relocate it manually and end the chapter then start a new one it resets the position to the default. I would recommend making it save the changed position and set it after a new chapter is opened or to be where it had been placed the chapter before.
