Some of these ideas may have already been said, so just ignore those?
Switch: A block that allows you to toggle any lights or doors connected to it
Flashing lights: Lights that blink on and off every few seconds
More decorative blocks: blocks such as vents, tables, chairs, cabinets (storage), beds, colored building blocks. These should get its own section in the shop?
Weapons: lasers, cannons, impulse ray emitter, flame thrower.
More shop types: Maybe instead of having one master shop, have 3 or 4 different types of shops that only sell curtain things.
Trading block: A block that allows users to place items (like a storage block) and when users come up to it, it acts like a shop and allows users to buy your stuff and you get the money. Make them so they are sold at full price, and when you sell things to a shop, you only get about 75% of its worth.
Clans: Make it so you can see all the members of your clan on the navigation, no matter how far, make it a permission or something so only higher ranked members can see, so that low ranks can't just see everyone. Or not, its up to you. Make it so you have clan options as an owner, such as friendly fire, and if true, and someone kills another clan member, all high ranks are notified of this action.
Warp drive: been said many times. You know what it is.
More types of thrusters, some for better handling/turning some for better speed, some for taking off on planets.
Select computers: When I go into a fight, some of my weapons will get damaged, and to replace them the computer has to be selected, or I have to select them then the cannons. Sometimes in a few of my ships the computers are stuck somewhere in the middle of the ship and its hard to find them, please make it so when you are in build mode, you can select the computers connected to your ship via an GUI item on screen.
Someone in your ship while flying: sometimes when I have someone in my ship and I am flying (speed doesn't seem to matter) even if they are in my gravity, they just teleport 1000+ meters away randomly. Please fix this.
Control block: similar to a switch, but allows you to toggle anything connected to it from the core in flight mode by assigning it as a number.
Lua support: please allow us to have computers that we can program with Lua, if you have ever played minecraft, and the ComputerCraft mod, having something like that in StarMade that can control the AI, and the ship and stuff would be absolutely amazing. This would take a long time to create, and I wouldn't expect this for a very long time, maybe even after the came has been launched as 1.0.
Creative mode: self explanatory.
Missions and things in single player mode: This is a cool idea that has been said a few times, but this would be fun, and keep the game going. Even if most of the missions where randomly generated from space stations and shops and things, or from random ships you may find.
Core monitor block: Gives you advanced information about your ship, such as the information you see in build mode on the left side. I like numbers and lots of information on the screen, but some don't so it might be good to keep it to a minimal then allow us to place a block like this to give us more information, and even add things like core heat and stuff then add a coolant block or something and the more things we add to the ship, the more head generated at the core.
Jet pack: Allows you to fly around planets, and faster in space. Requires power, can be charged from a charging station, another block idea that has a single inventory slot and draws power from the ship or something to charge things like a jet pack, or maybe body armor.
Clan announcements: allows high ranks to make announcements to their clan members in game, once the announcement is made it is shown on the top right as a notification, then can be found in the clan tab.
Server message: an option in the server config to set up a welcome message for its players, that can include server rules and things.
Help command: gives you the commonly used commands.
Those are most of my ideas. I hope you like them. Ill add more as I think of them.
