Draft patch 2, working toward "wrap on word, else wrap on character if word is
longer than the visible space". I can see that this breaks arrow/end/home
navigation inside the text input field ... big problem. I'll stop the insanity
here, rather than trying to reinvent the wheel.
Final application is calendar-like. I'm looking for a widget that wraps like a
text editor, but is light enough that I can dynamically generate and move
80-100 of them at a time, often, for just a few lines of text (1-10). Font
styling not really necessary, so I figured the multiline input would be best.
Other ideas welcome!
