A few suggestions:
Barracks - please consider either a 12 hour x4 Mr Myers equivalent buff, or a Barracks #2 specifically for say Elites, Cannoneers etc.. (the units that take longest to train). With the advent of the FT adventures, its soul destroying to have to wait so long to replace lost troops. And let's face it, anyone who's not lost Elites and Cannoneers on these advs is extremely lucky....
Population and Storage - please can these both be added to the economy tab so we can easily locate any of each building that we may want to upgrade?
These are only my suggestions, if you have any improvements on them please do feel free to add them
