Just FYI, I've pushed a fairly big update that adds the following features:
- an rtglgrid that operates row-wise
- messages to get cell, column and row state: "say col row", "csay col",
and "rsay row"
- "size" message to dynamically re-size the grid
- a properties dialog where one can set cell size, spacing colors, and
grid dimensions
- a more colorful and better organized help dialog :)
It should load your old saves fine, please let me know if it doesn't.
Hope people find this useful, and thanks for the feedback so far!
