Just thinking that a good enhancement (for me at least) would be to save your Simulgear orders without committing them to being your turn.
For example, on the Operation Citadel tournament, we had a week long timer and it takes me a while to put the orders in... sometimes I like to plan out a turn and "sleep on it" and make changes/tweaks later. When you can have up to 30 attacks and 3 reinforcements, it'd be nice to be able to keep it instead of having to retype them all in all order again.
I can leave my laptop and come back the next day and at times the screen will "remember" the orders, but other things the screen will just lock up (or my laptop will reboot) and I lose the orders.
Hmm - I think it risks slowing play down if this is added.
