Autodoze-
 *Do not autodoze for roads,rails, or wire if not enough money to actually
  build it

Budget dialog-
 *Press escape to close

Coal powerplant-
 *When third tile of second row is on fire, something appears to revert it to
  the animated smoke stack.

On Game Load-
 *All zones are unpowered for the first several ticks. I'd imagine there
  are similar problems with the landValueMap, pollutionMap, tfDensity,
  policeCoverage etc. I think what should happen is that the various methods
  that update these maps should be called at load time.
 *Evaluation data is not available.
 *cityTime may not match history.cityTime

Mouse pointer-
 *Would be nice if tool dragging would help keep lines straight

Disasters-
 *When running FAST or SUPER_FAST, automatically pause or slow down the
  simulation when a disaster occurs.

City size notifications-
 *Pause and pop up a message the first time the city reaches 2000, 10000,
  50000, etc. people.

Code janitor-
 *Rename fireZone() to killZone()... (I think that name might be better description.)
