I have some questions about CTP 2 which I couldn't find answered in the manual :

-Where can I find more detailed descriptions of what things (especially wonders) do (in the library it just says e.g. "increases science" but of course I want to know by which amount) ?
-What is a "research pact" (can't seem to offer it, but was offered it by foreign civ.) ?
-How can I view the composition of enemy armies ? If you move over it, the contents of the stack appear rightunder, but this space is very limited and can't fit all unit names.
-Is there a possibility of having a warning appear when you accidentally move a unit into (attack) another civs one with whom you are having a peace treaty ?
-Where can I find how much gold I have ?
-How can I see which trade routes were pirated and where ? (I know this appears in a flash during the other players moves, but usually this just goes too fast)
-How can I switch between the tabs in e.g. the Empire Manager with the keyboard ?
-Do existing trade routes take less caravans when you improve the roads ?
-When I build a wonder which puts an improvement in all cities (like e.g. the Internet), do the already built improvements of that type (e.g. Computer Center) still count (improve things)? (I know they do for the upkeep)
