I made a screencast of the current prototype.
You can watch it here on Youtube.
Some of the major current limitations:
- Lack of support for Undo/Redo
- basic cursor motion when editing presents issues (e.g. cursor anooyingly repositions itself at beginning of box while editing - this is why, in the video above, I use pasting instead of inserting single characters).
- advanced cursor motion among boxes at appropriate user input (e.g. when cursor gets past end of text in a box it could reappear in the next one)
