Contains my proposal for changing windows' layout.
Original: Hard to read, superfluous text, inconsistent number of decimals.
My proposal: Right aligned, complete number, no decimals, no currency marker
Same as "Money Stats"
Knowing how long it will take before the required amount of ore is harvested informs you what to upgrade first.
The original shows arrows going DOWN which is counter intuitive to the action UP-grading.
It is not always the cheapest mine upgrade that gives the largest extra output per invested coin. Hence the "Price per" column.
Instead of the "Mine Upgrade" window. Showing the upgrade consequences directly saves a lot of clicks. The question is only if it takes too much space.
"Un-dug Dig Sites":
The current situation where a click on "Dig" removes the window with the list of un-dug dig sites is annoying if you have several un-dug dig sites and you are looking for one particular. Then you need to open the list again and again until you find the dig site you want.
My solution is simple: Show the information for each dig-site in a short hand notation.
"Army Camp Upgrade":
Just like "Mine Upgrade" this could be implemented directly in the tab or in the upgrade window like this example.
Just like "Army Camp Upgrade". The text in the head of the upgrade window could be moved to a button on the tab or on the tab itself.
Bearing all the hallmarks of a half-hearted attempt to provide stats of some kind. Speaking only of the UI: Everything is center aligned. Number precision is all over the place. It is virtually impossible to see what is in progress as numbers 1 and above is drowned by 0's.
The content, type, and number of columns is another kettle of fish which I will not touch here.
My proposal for cleaning up the window and make it somewhat legible: Left align text not in headers, right align numbers. Show only 3 significant digits.
And move the close and refresh buttons to the bottom of the window where these buttons are on all other windows. The name of the game is consistency.
Like "Recipe Stats" the close button should be relocated to the bottom of the window.
