Related to a discussion about market maintenance and bricks, this is a general UI improvement idea I think will help a lot. Like the gold displays both current holdings and monthly change with a drop down list of details, I think all the other resources used for maintenance and construction can do with something similar.
First off, to make more room for this, you will need to double the height of the top information bar. Then the gold Change value, along with all the other items can be listed on the second line, which means gold won’t have to be so wide. They will each have a drop down showing the number of materials consumed by maintenance each month in addition to production and construction. Production can be twofold, consumed and produced. This only needs to be displayed for any item that may be required for building maintenance. I don’t see why firewood would have to be pulled since it is consumed for both heating and production.
The medical indicator at the top is hardly useful but it could certainly be narrowed quite a bit, giving more room for things to slide left. The happiness one too since it has no numbers to show.
Another approach might be to move the seasonal calendar gauge over to the left and drop medical, population, happiness and food down below it. This will make more room for other resource items along the right side as it would look awkward to put them below the calendar gauge.
