I’m not sure if this is a bug or a design change, but once upon a time you could mouse over the bars down at the bottom of the resource window and see various breakdown information. I didn’t use them a lot, but it was sometimes useful to look at.
I especially miss the one where the “percent of fully-stocked houses” had a breakdown for subcategories like luxuries (important), firewood (very important!), and food (honestly actually much less dire as long as people had food) so I could know what things needed a larger buffer of supplies.
It was also sort of nice to know whether storage was half-full because everything was half-full or whether it was because a few were completely full, without scrolling around looking for barrel icons.
