Here's what I posted about my modified source files, 2011-09-20-TexToys-modified-source-files.zip, on the Yahoo group. Each set of modified files is accompanied by a Word document which lists (most of) the changes.
boxup = the feedback box is raised so that it is less likely to cover the text
window_close = when the exercise appears in a pop box, a "Close window" button is provided. (This is not relevant in most situations but won't stop the exercise working normally.)
dictation = no freebies (each instance of a word has to be typed in)
reading_text = a reading text field is added (similar to those in Hot Potatoes)
punct = students are not penalised for typing punctuation characters
text_recon_classic = you get the the freebies
subtitle_field = moves the contents of the subtitle field to the "reading text" position
vowels = all the vowels are removed but the consonants remain
new_score = Scoring anomaly in QuizPort corrected by Gordon Bateson, see WebSequitur - Scoring anomaly
wide-reading-text = the "reading text" is wide enough to contain a big picture or video
In several of the modified WebRhubarbs, the text field has been made resizeable so that it's possible to easily enter more words at a time.
Thanks again to Martin Holmes, Patrick Verguet and Gordon Bateson for providing me with the code to make all these changes.
Don't hesitate to contact me if you need help.
Here's an example with a "reading text" on the left, a resizeable text field, the feedback box moved up and the vowels removed: Skateboarding.
