I'm not married to EUI yet, even though I'm using it. Top panel is most important, then the unit list. Being able to see enemy unit promotions is a must. City states on the side are great, and so is hovering over a city. I thought I would love the terrain tooltips for settlers (reason I got it) but they're really so clunky. I also don't like anything about the city view except that it's easier to purchase and queue build orders.
