UPDATE: Generally finished coding. For the sake of completeness I am only implementing gamepad controls for selecting ships - which I have to simulate with keyboard cause I have no gamepad
UPDATE: Phew, implementing gamepad support I screw mouse interface

. 2 days lost but fixed and already preparing nexus mod page.
Little teaser

:
ENGAGEMENT
1. At start of combat name of leader, its stance and weapon will be displayed.
2. Rest of ships are presented by name, ship icon and HP bar in order of aggro (same as prior to launching). They are called supporting ships.
3. Modules are activated by current leader so their availability depends on his stance.
NEW STANCE MECHANICS
1. Stance of attacker and of target ship can be different. Therefore stance no longer implies symetric aim penalty/bonus to the opponent.
2. Symetric penalty/bonus to opponent has been replaced by other buffs/debuffs.
3. Leader/UFO on DEF has 30% chance to dodge any hit.
4. Leader/UFO on AGG has 30% chance to 'be hit by a miss' - that is 30% chance that a miss against him will turn into a hit.
5. These are customizable parameters.
CROWD IN THE AIR AND QUASI-FORMATIONS
1. Beware 'lone bullets'

2. When UFO misses the missed bullet is considered 'lone bullet'. It missed the leader but it can hit supporting ships!
3. Supporters on BAL stance have 20% chance to be hit by a lone bullet (customizable).
4. Supporters on AGG have 40% chance to be hit by a lone bullet (customizable).
5. Supporters on DEF are safe from lone bullets (hard coded).
6. You can now think of quasi-formations like:
a. Tanking (easy) - leader on AGG, supporters on DEF (or BAL). UFO picks AGG with +15 penalty so rather hits leader, producing few lone bullets.
b. Mice and cat (difficult) - leader on DEF, supporters on BAL/AGG. UFO picks DEF with -15 penalty, rather missing leader and producing many lone bullets. Beware supporters!
c. Evasive (easy) - all ships on DEF. Lots of misses, lots of harmless lone bullets but jets have greatest chance of returning untouched.
d. Blitz/Berserk (easy) - all ships on AGG. Similar to tanking but whole squadron on AGG hits as hell with 30% chance of turning any miss against UFO into a hit. So does UFO...
