#327 tts toolbar improvements

[hgkamath]

The TTS toolbar overlay obscures some text or images underneath it, which can become hard to read/see. the TTS toolbar also occupies display real estate. Though usually the highlighted sentence, this may not always happen. Also sometimes ebooks with images could be such that the tts menu obscures the image. The sentence reading is such that not only is image obscured, there is very little time to glance the image and understand it in context, and the high-lightening moves to the next page.

suggested improvements

• Instead of overlay, it is preferable to shrink the read-view and dock the toolbar, that way nothing is obscured.
• The toolbar can be made very tiny. It is understandable that different people can have preferences for tool bar size and buttons, and may depend on device, so maybe TTS toolbar size this can be a tts-preference-setting.
• The voice and and pitch scroll bars and other voice parameters are often not used in session, so most of the time they are occupying space. A extension button "^" can be introduced to toggle between an extended TTS-toolbar and a minimalistic toolbar. The extended toolbar does not have to be a tool bar it could even take one to TTS preferences/settings.
• the button '||' / '|>' '<<' '>>' are frequently used. The stop button '[]' is synonymous with close TTS mode and end-session. Perhaps putting an 'X' sign over the stop sign as in '[]'. shrinking it and making it look like a close button '[X]' . SO I think the buttons ought to be a tiny bar at the bottom as '||' / '|>' '<<' '>>' '^' and '[X]'
