Option trader should allow us to set up combos and then adjust them by strikes or expirations, rather than having to set up the whole combo again, which is an unnecessary hassle. TOS allows this, it saves so much time in fast moving markets. Option trader should also have have the flexibility of putting in a price or date we wish, and see how the the profit loss / performance profile changes as a result. it does show a performance profile but only with the current price, IB developers please do this and let IB lead again.
