1) Plot Yield Modified Plot Yield is not so straightforward. There isn't a getExtraPlotYield(xxx) command, so what you see is actually tedious calculations based on terrain, subtracting improvement, etc. Thus, saving it is a chore. I remembered attempting to modify plot yield on that save file before and it CTD, so chances are it is unlikely to happen. 2) City Leader Icon Doable easily 3) End all players Not sure if it is actually needed. If my game hang, I definitely want to know who is the culprit, so I will want to end each player one by one. Adding such a function is doable, just a matter of layout. 4) Mouseover Doable easily 5) Wait/Fort/Finish Status Adding another column is doable, which then makes the color coding unnecessary. If necessary, that page can be broken into 2 separate ones, for units and cities so that each can display more sortable data, such as population, culture level etc for cities. Busy these few days, so wont happen too soon.
