What irritates me a bit is the way the reading starts.
First it would be nice if squirt waits for the user to set some settings (Speed, etc).
It also would be nice to replace the numbers "3, 2, 1" with something graphical, because they are not part of what I want to read. Maybe a centered bar what shrinks towards the center from both sides and makes the user focus on the center. When both shrinking ends touch each other the reading begins.
