TBoard: Letterboard AAC Typing

Worksheets you photograph are easier to turn into a lesson. Highlighting no longer has to be done in one stroke: lift your finger and carry on, drag an edge to extend or shorten a selection, and tap single words or whole lines. Passages default to lines and questions to words. Two fingers pan and zoom, Fit page resets the view, and a typed correction is kept until you replace it. Scanning a worksheet keeps every page you capture, in order, and a page that fails to read can be retried without photographing it again. Show answer key: a new lesson option, off by default. With it off, the lesson reader no longer offers a tap-to-reveal answer to the student, on daily lessons and on Practice and Graded worksheets alike. Turn it on in Lesson Settings before a lesson, or in the reader's Lesson options. Fixes: tutorials and one-time tips no longer come back after you have been through them; a confirmation no longer closes itself before you can answer it; dialog buttons no longer cut off their own labels; the week's practice chart opens practice stats rather than the gradebook; and signing in restores saved lesson sessions that could previously be skipped.
