It would be nice if we could auto-hold torches in the off-hand in place of a shield, regardless of the one handed weapon in the main hand. It could be limited to not allow two handed fighting unless the main hand is a light weapon, or the character has Two Weapon Fighting, that allows two melee weapons to be wielded and used. It could also, when not usable / used for two weapon combat, provide only a +1 to AC rather than the +2 a shield would provide.

As for flaming / flame dipped weapons, let us put the weapon away instead of having to constantly carry it unsheathed. Even with a flame dipped weapon, my character is doomed to forever carry his weapon out, even after the weapon no longer is flaming.
