Alternative actions submod from extras is now deprecated and will have no effect. As long as screen width allows, game will now display additional panel with all possible unit actions. Panel will also display spells that can be cast by unit, allowing small version of unit spellbook (total limit of actions is 12, but some are used for creature actions, so unit spells are limited to 7-9)
