I have a single suggestion for now:

Allow a texture to be loaded into an LCD that displays the current shield level in real time.
(similiar to when you type ':' in the shield gen block name)

If there's a mod that already enables this, I'm all ears.

That script is being worked on now as stated just before in the main thread for this mod.... EXCITING

I Think it could be really cool if it would be possible to make the shield visible when a meteor or a bullet hits it. (I'm thinking of how it looks in Star Wars ) :)

Is that possible?

As a suggestion I think that the style of shield that you have at the moment is no fitting with the style of combat in SE, you shields are more suited to an active combat style while space engineers is a very passive style, where more armour is rewarded better then welders everywhere. I’m by no means denying that your work is AMAZIN, we have needed shields in SE for a long time, but I just don’t agree with the style of shield, and would have gone with a high cap low charge rather than low cap high charge style. perhaps having 2 types so people can choose?

A shield hardening block that reduces the alpha damage of incoming fire would be cool, and having it work on a formula that makes each new one add less benefit then the ones before it (either a linear or exponential decay effect). It could be either a fixed amount of alpha reduction or a percentage, whichever would be better for balancing and would naturally eat up a bit of power. If working on a percentage, it could help alot against the ridiculous power of modded weapons to some degree as well.

You could also balance this by having it work as a modded battery so it would only be usable for a certain amount of time before needing a recharge, so its useful but not OP.

Perhaps a new class of weapon that performs massive damage to shields, but only minimal damage to armor? People have been lusting for energy weapons (what better to hit an energy shield with?), Star Trek phaser imitations have been made… Perhaps one of them can be turned into a turret, and be the counter to energy shields.

An EMP Shockwave block (or turret mod) would be awesome

A boost in shield resistance to incoming fire would be good since small arms rifle fire can drain shields somewhat effectively if kept up long enough on lower shielded ships, while a single tungsten shell fired from MWI's Mk3 battleship cannons can drop a 250k shield to nothing and start piercing into the hull. I had 6 generators, 24 capacitors, 24 coils, and at least 2 layers of light armor since the ship I tested on is still in the planning phase. 1 shot, BOOM! right into the hull's outer layer.

i like the idea of a shield core mentioned above. more of a control computer, a block that has slider bars to tune your shield array, and output status. the shield generator makes the shield, capacitors increase capacity, boosters increase recharge, efficiency modules decrease overall power consumption, effectiveness decreases down time when shield is broken, productivity lowers the charge/capacity curve (because the closer you get to 100% the slower it charges). so from the core you can tell it to stop charging at 50% capacity, drop recharge to 25% max to reduce power consumption. power consumption should scale, low power to maintain small capacity, increasing with the increase in capacity. when charging the power consumption is higher, scaling up the faster you try to charge them.

a power usage setting in the .cfg file might be nice too.

I have some balance suggestions:
Make shield's power scale down with the number of blocks it's defending:
If you have a big ship to defend, the energy shield will be "split" on more surface and therefore be weaker.
Make shield's power not linear but logarythmic, so that after a bit it becomes useless to add more shields.

I'm suggesting this because otherwise the game would become a race to get as many shields as possible, with a logarythmic scale you penalize overstacking them

hay these are all really good and i have another thing for anti shields
:Note All armor DMG rateings are for small ships unless stated other wise And most weapons are small ship/Turret:
:Note on Dmg rateing Low Dmg To large ships is sort of like one rocket to large ship light armor:
------------------------------------
EMP : High Shield DMG No Armor DMG
Has Mid ROF
-----------------------------------
Plasma : Mid Shield DMG Low to Mid Armor DMG
Low to High ROF
(Depending on Plasma Weapon EG a Plasma Rife \\Hand Weapon// Has Low Armor Dmg For Small ships And High ROF But a Plasma Luncher \\Hand Rocket// High Dmg For Small Ships Low Dmg For large Ships And Low ROF)
-----------------------------------
Beam : Low Shield Dmg Low Armor Dmg
The Lowest DMG Weapon But makes up for it with insane ROF And HUGE Bursts
-----------------------------------
\\Tech Shell Weapons//
-----------------------------------
Shield Bore Tank Gun VERY HIGH ARMOR DMG against UnShielded Targets mid Armor DMG against Shielded Targets And Very Low Shield DMG
Good Weapon as As it has Fair Armor Dmg That Bypasses Shields how ever this is becuse most of the stoping power is used bypassing the shield
-----------------------------------
\\Support Things// (Shields to)
-----------------------------------
Hard Light Shield : A Large sized Small Ship Deployable Cover Acts as Foot Soldier Combat Cover
:Blocks Light Weapons EG Gatlings Also Dose not take extra DMG For Anti Shield Weapons How ever has much lower Armor and can easly be Taken Out By Explosives
:Blocks Bullets Like A BOSS (AKA Little Shield Dmg Form Auto Rifle (0.5) Gatling is 1.0 pershot)
-----------------------------------
i Have more ideas im sure but its 11:00 pm for me feel free to add any thing also if any of this is not possible its becuse most of the stuff in the OP was stuff that would be cool but ye Good night (for me at least)

I just tried this mod today and I love it, I have been wanting shields for a long time, but it is way too weak. A single shield generator at full charge can only hold off a few small ship rockets. The current strength is nowhere near enough to be of any use. Even small ship machine guns can tear through the shields in a couple of seconds. I have not even tested it against large ship weapons but I can assume that the shield would not make any noticable difference in battle.

If you look for the config file from the mod you can tweak the values for capacity and regen rates. from within the users folder, go to app data (check folder options to show hidden files if needed), roaming, space engineers, and I think it was in a folder named storage. For mine I've got them set at 10x value for large ship generators so a single generator with 4 of each module on it gives 500k but small ship just currently uses 4k shield and a 100 point regen rate.

For the ships that have enough room inside I do a 4-block high generator with an even split of modules in a staggered pattern around it and that gives 1 mil shield though its not exactly fast to max out.

I tried this but I can't find the appdata folder

I found out the issue Alpha. Go up to the tab at top that says view and check the box with hidden items.
