My "concise" idea is to code into your attack generator an option to attack from 3 (no more than 3) different places all from one command.
Since the code is already written to generate an attack, it appears easy to add to the existing algorithms in order to have one, two or three attack options for each turn. In essence, there would still be only one attack; however, It would be wonderful to be able to attack from Alaska, Greenland and Java all at the same time.
We might use 3 "attack from" menus and 3 "target" menus, or we could use one "attack generator" and three "targets designator" with three options: attack one on one, two on two and/or three on three.
I truly believe this would, essentially, "speed-up" the monotonous mechanics we've all experienced taking opponents armies to sweep the board. I believe everyone (75%) of the members would welcome the addition.
I believe this should be a priority 4.
Test the water and get some feedback on this. I haven't found anyone who has even mentioned the possibility of this option(s).
Best wishes,
