Just an idea, but, concerning the bottom icons...
Microsoft/Adobe products have multiple toolbar combinations that one can add to the default or make the default. One can choose the drawing toolbar, or the animation toolbar, etc.
If there is future thought given to an optional larger toolbar, then could that be switched to optional toolbars? A player could switch from the movement toolbar to the attack toolbar (artillery, op-fire, smoke, etc), to the organization toolbar, etc. Some toolbars would contain redundancies, next unit, for instance, found in several. Toolbars could be toggled on/off either through keystroke commands, or by hotlinks common to all toolbars. Clicking the "A" icon on any toolbar would switch to the attack toolbar, click the "O" icon, switch to the organization toolbar.
I know some web programming, and the hardest part would be the actual graphic creations, then the linking, but absolutely doable. Not sure about how difficult (time consuming) in the game design world.
Again, just a thought...
