New user, new(?) questions

Hi, I've been lurking a bit, but I figured I'd join and ask some questions etc. that have bothered my mind. Any answers would be appreciated. (All are based on stock game)

Bolt weapons
1) On some games, I've noticed bolt weapons to have clearly better accuracy then they should against targets that stand still, or are on direct approach vector (head straight towards).
The shots deviate, as if they were supposed to miss, but still hit the target. Are bolt weapons supposed to have some sort of "second chance to hit", with anything colliding with the bolt taking a hit? It seems to work like that.

2) As a trial, I edited a long range bolt weapon that had a really high rate of fire. (reload time 0.1 second, just wanted to see how it looks like). The bolt seems to have 3 possible "headings": one straight to the target(which on a fast moving targets causes the bolt to curve), one below, one above. The gun created a three "lines, one heading to the target, one above it and one below. I know it would probably be of little use, but would there be a possibility to get the missed shots on bolts to scatter? (randomly offset the x and y aimpoint) This would create a bigger deviation, and could also be used to present area of effect damage by some modders (I understand AoE damage is not planned for now). I assume the "bolt shot" object contains it's target information, so randomization would only be needed when the shot is fired, and depending on how the heading is set, this might be quite easy edit. Can this be done by the modder in the gun properties (I didn't find anything indicating it could be done, but might have missed it)

Seeker weapons
1) Seeker weapons seem to ignore the "% damage targeted" rule of targets. If you have a strategy where the first targeting priority is damage related it reduces the overkill on bolts and beams, but all seekers seem to still be fired on same target, so the seeker damage capacity is not taken into consideration(I guess because it can be shot down so is unreliable). This can lead to serious overkill with seekers. Can seeker damage be easily counted to the damage? I'd like the idea of using fleets of missile ships that split their fire and not fire all seekers on one target, and then overkill it by factor of 10. Other option would be letting seekers re-target if the original target is destroyed.

Beam weapons
Beams seem to also have the same hit-miss above-miss below effect as bolts. Could beam misses also be scattered? I guess that would happen automatically, if bolts get the target change. It's a small thing, so not very high on priority, but could be nice spice up.

Enemy designs
Would it be possible to add a filther to design view of "enemy designs" (and units) which would be based on time (since the design has a note on when it was made)? For example, filther "before date" and "after date" would be good to find the latest enemy cruiser from a group of 30 almost identical names, when you want to check what they have. Even arranging them date wise would be nice. Is there a way to do this currently, and if not is it possible to add such feature?

Own designs
I've noticed a obsolete problem with the treaties: I have a treaty about design sharing with empire A, who has same treaty with empire B, who has the same treaty with me.
When my design gets obsolete, one or both of my allies send me designs of "new enemy ships" they have seen, my obsolete ones. So I et neports evey now and then telling me the designs of my old ships. I'm not sure if all three empires are required for this to happen, or if it also happens between you and one empire.

PD weapons. (collection of PD related things)
Order "hold fire" also stops PD weapons from firing, while "auto targeting" opens fire on all weapons(manual combat mainly). If you wish to not use the "main weapons" (like on planet attack, or ship capture), but still want to keep PD firing on any seekers they launch, you have to some how trick the main weapons (target them to another target that is far outside range or something similar). WOuld it be possible to enable some sort of command for "PD fire only"?

PD weapons seem to targeting seems to work pretty well on later versions, one problem i have found is that if the ship has multiple PD weapons, only one will target each seeker. This is good, until the one firing at seeker misses. Then the seeker hits into the ship/planet before PD will reload (unless using PD blaster), while other PD weapons stand there waiting. Would it be possible to do the following: If PD is firing a seeker, after it has fired the targeting is cleared (so it will no longer target that seeker). The targeting is cleared at the start of reload time. This means the seeker is not targeted by any PD weapon, and if there are any other PD weapons free, one of them will lock on and fire at the seeker as if it was coming into range normally. I think this would improve the functionality of PD, and would not require much coding. (the relock on is already existing in a form of original lock on, all that is needed is the target clearing. for PD that has fired and missed).

PD missiles suffer from the seeker overkill problem: All PD missiles are fired on same target, so it will not be very effective form of PD.

That's most of my game questions (for now)
For modding, I'd like to know these things:
Is there some manuals of the commands and functions? I tried to lok around, but didn't see anything. (I have the European version of the game)

Is it possible to make a facility that would increase the scrapping efficiency of one type of unit only? Like only increase Drone scrapping efficiency? If it is possible, how?

And last, have you ever considered holding a AI competition?
Each player would make a AI empire, then they would be set to a game(random conditions) fighting against each others. Maybe few runs with different set ups, and winners would get a prize (and the winner empires could be put up for download. This could improve AI, and make AI:s very different.

Well, that's all for now. Thanks in advance for any answers.
