When marking a room for a specific purpose it becomes shaded out. While I get why this is done I wanna ask that it be changed to a different color for the room type you are hovered over while in the Rooms menu. A color like cyan/light blue or bright yellow/green/orange would probably be most effective for this.
It is incredibly difficult right now to find the lonely square that occasionally causes the Todo message "A room in your prison does not meet the required criteria." While I know in most cases this causes a flashing red triangle with an exclamation point to pop it's not always easy to find it when you are building a massive prison.
Also of note is that right now I am on one of the Prison Warden maps and may be a bug of a similar nature tied to the bug I keep getting about some of the areas of a prison being without power on the Prison Warden maps even though nothing is flashing saying they need power.
