Hmmm, though I guess "show info about a civ during embark selection" is a separate suggestion
It is, and one that applies to more than just this one topic. (I think I've made it before? Searching says apparently not...)
It's a problem that you don't have the ability to see anything at all about your civ without backing out and using Legends Mode first (or going through Legends Mode beforehand), and it's generally a problem that the screens that give you information are totally divorced from the screens where you make decisions, causing players to too often "fly blind". (I'm thinking of screens like military and burrows at the moment...)
Something I'd also like to see without having to return to the title screen is the materials that a civ has available, both at embark, and for trade, as well as just general health of the civ, and who is king/queen. (Surprise, your queen is an elf!)
... err... Sorry, I think I went and commented on the wrong suggestion.
Anyway, to get back to your real suggestions, this is generally more of the same problem - that the menus are unorganized, and that they do not link the important information about the decisions you are making to the actual screens where you are making those decisions. Unfortunately, design philosophy flaws endemic to DF.
