Can't get a tooltip for required materials icons

[Larry]

I'm curious if there's an in-game fix for this... When preparing to build a new building, the info screen for it shows the required materials... and (at least while you are first learning the game) it can be sometimes hard to tell what the shown icons are representing (ex. the Soap Shop building indicates it needs three items, yet one of them is unfamiliar to me (currently)... kind of yellow blocks.

So, normally, you would just hover over whatever icon, and get a tooltip... But, due to how the windows work for the Build screen, moving the mouse towards that icon causes the window to close/disappear... and suddenly the world as we know it is a bit less happy.

Not a code red, as I could/should just fire up a wiki, and look up that icon... and leave all you good people to continue playing. But, I figured I'd ask if there's some in-game means to identify those icons. I suppose closing the window and maybe opening the storage window?

Kind of wish I could just somehow hover over the building's info screen... kind of save myself the trip.

Otherwise, I'm generally loving the UI of this game...
