1- city last production bug fix (eg. "City X has completed Y", where Y must be the actual last completed build!!)
2- unit movement turns required (when it says "3 turns required", it must be correct. It doesn't take into account several factors, like extra movement. When it says a unit can attack this very turn, it must be true)
3- show unit current movement (a unit set to "Go to" somewhere should display its current path, when selected. Otherwise, I can't tell whether it is still in place or moving somewhere, and where)
4- city yields modifiers/bonuses details (eg., about production: +15 from tiles, +3 from buildings, +15% from buildings, +15% from policy slots, total 23.4)
5- city buildings and districts bonuses (when hovering on a building/district on the city screen, I should see details "+4 faith, +2 amenities", etc).
