Even just sm-accessible dialogs for transferring minerals or missiles would really be useful. For minerals, one currently has to manually add and remove them to populations when doing a trade. Missiles currently have to be loaded into some ship, the ship transferred, then unloaded, and then the ship transferred back (or removed if it was a temporary one), and then you have to remove the ship class from the other race. Also useful would be a way to sm-transfer populations without any technology transfer happening, and a way to set population status (subjugated and so on).
