Request: Add textbox below

[mcodr]

Hi,
Please add a text box below that contains the whole text being read without losing format and highlight each word being read while playing/reading.

This feature is found in an old windows app called Dictator written in python. However it does not implement focal letter highlighting and the spritz like reticule.

An android app also exist called, "Speed Read inspired by Spritz!" created by Reinhard Strauch. However, the android app stops working with longer txt files. Otherwise, it would have been nice if it can be ported to other OS.

Thanks & keep up the good work!
