Just one extra part.

[davieholgate]

Decouplers with pushers for the times when struts cancel out the separation force.

And.. an air compresser with tanks to fill that can be used for anything. Always welcome more means of propulsion.

you should try using the Seperatron boosters, angle them prograde and they will thrust away dropped weight

[davieholgate]

There was a very popular mod that added plane parts called "C7 Aerospace pack", and lots of people loved it...

in 0.15 we got planes.

that's because C7 was employed to make it

[InterCity]

A rockomax equivalent to LV-Ns

LV-N is just not enough to get my huge payloads somewhere far.

[Koen]

Add me to the motorized hinges wishlist.

I know there are some great mods with such parts but I don't like the idea where everyone is playing a different game.

[inigma]

Stock EVA attachable fuel lines.

[MC.STEEL]

All i need now is something realy raly simple,want to know what it is

Its a 2.5 m hub

i fail at station desing without it

[Highlad]

I want a science storage container.

Something that is light-ish and mobile. so that, when I am doing science around jool, I can load up the storage container with my experiments and send it back to kerbin.

Basically I want a more weight efficient way to bring science home. Something more elegant than bringing the whole ship back or bringing an entire crew pod back.

A powered hinge of some kind, so you could make foldable things. Imagine all the stuff you could design with it.

Why not just use the one-kerbal lander can? 0.8t, stores experiments. Just stick an engine on the bottom, landing legs, and chutes on it.

[Whirligig Girl]

Robotic Arm.

[Goodiej17]

A paper bag. So the Kerbals have something to use when they start to hyperventilate as the rocket explodes under them.

[3mon]

Something that can tell me the DV and TWR of the ship, although it should be integrated in the UI and not a part :/

[Spartan125]

A solar sail.

[Wjolcz]

A camera that allows you to make panoramic pictures and "crew reports"

[Seret]

Radial nuclear engines. Attaching with the current radial part options is fugly.

[pigletx2]

A small, light, 1-kerbal lab. But it would be slow, and take more electricity.

[ARC25565]

A flexible hose that a kerbal could pull to refuel craft at bases ect. It could transfer all types of fuel. This would make it a lot easer to refuel ships on planets. Also you could have a power transferring version to recharge ships and rovers.

[SkyRender]

Not so much a part as a feature I'd like to see in stock: an in-VAB/SPH tabulation of per-stage mass/dry mass, and even pre-calculated delta-V if that would be possible. So basically, what the Kerbal Engineer Redux chip gives you.

[0muffins0]

I have to agree with ARC25565. Having a flexible fuel line would be awesome since refuelling on the ground via docking is very, very difficult.

[CommandantAce]

Structural wing and wing connector with the attachment points on the other sides, so that we can attach via the short sides on both. I guess that is two parts

[dnugroho]

A surface sampler for unmanned probes/landers, for sure. This will help me sampling the surface of Eve without having to sacrifice Kerbals there.

[RSwordsman]

A Woodward impulse engine on a 360 degree gimbal. Forget all this re-orienting the ship and burning fuel for little adjustments; this (theoretical) puppy makes it happen at any attitude as long as it has power!

[FlamedSteak]

A servo arm for lateral surface docking. Failing that a sampling scoop for rovers.

[DJEN]

Huh, looks like many ideas already came out.

As for me, an engine with great gimbal capabilities would be satisfying.

[sgtscuba]

A servo arm for lateral surface docking. Failing that a sampling scoop for rovers.

^ this would do me. Would love to have an arm to use like the Canadarm so that its easier to build stations with.
