Just take a look at AoE II for example.
I know that people requested stuff for the minimap since ages (no icons, alerts)
but what about visual and audio cues when stuff is being built completely? you know like in every other rts ever, i know it is somewhat possible with Washy's notifications mod, but what about more?
Also, i cant seem to find a generic "cycle factories" hotkey in hotbuild. maybe im just dumb and should learn to use control groups, and yeah "cycle idle factories" is also nice, but isnt there an alternative possible?
