So many times a mine, water, wheat field, etc. will become exhausted while away from the computer. This happens to me several times a day and unless I hear the audio crash then I won't know about it and therefore have to review my entire map when I come back. Kind of a waste of time and effort.
It would really be nice if the pop up message, informing of the exhausted item, could remain up and allow us to manually close it with an "X" option up in the corner of the message. This way when we returned to the computer we could see the message and remedy the situation quickly and efficiently.
Thanks.
