- No auto-complete.
- If you close all windows, no window is opened on next launch.

- Line height calculation (for scroll-past-end behavior) does not account for font.
- Undo stack should be cleared whenever new stuff prints.
- No way to export history as, say, RTFD or HTML.
- Control codes aren't interpreted. (http://www.pixelbeat.org/scripts/ansi2html.sh)
