Seconded!!

Even without hovering over settle (to plan out a game with easily available information without going through unneccessary UI-Hops)

Imo there should just be an option/overlay to show tile yields. Standard since Civ 1 / Mom. I see no need to deviate from that. The graphics are allready in. So why not have an extra tab / minimap-tab who does that... Yes tile tooltips does this but scanning all tiles can be tiresome... (fine for beta, doesn't feel alright for a finished product).

There are much bigger things though (Mostly OOM and crashes which are way less of a problem than in WOM but the most glaring thing around right now), lots to balance and polish.

I don't know that it's buged. I read a dev saying that if the tile is too close to another city it won't bother showing you the yeild. aka, the game only shows you the yield of tiles that you can construct cities on.

actually, there is supposed to be such an option (it's a tiny unmarked button in the upper right of the screen that also doubles as the place where it sometimes says "swamp" or "forest"), but clicking the button has almost no effect.  I say almost because if you clear a bandit lair or ruined caravan and click the button, sometimes you can see the yield on that one square.
