I just read through this whole thread and what makes me laugh is the attempt to coordinate efforts to keep everything at it's best. . . instead of just remembering what was low the last time that you clicked and click that next.
There are two things I have always thought this site/game was missing: a "snapshot" button so that you could save views of the city over time, and an indicator of some sort to let you know where the most recent change was made (eg: which house is newest or which building increased in size).
It amuses me for some reason that this city has existed for, what, 3 years(?) and no one here has ever posted in the Bulletin (unless the messages go away after a while).
One more thing (I mention this because I didn't see it in this thread). Did you know you can zoom out (but not back in) if you press the "1" key (above the letters, not the one on the keypad)
