See block name/number

Can someone tell me how I can see a placed blocks name? It's impossible to know which light or which rotor is which from the control panel

You'll have to show them on the HUD... it'll get a bit cluttered, though.

I just name them as I go.

good tip, thanks!

To expound on Evil's comment, you have a "show on HUD" check box on most functional blocks' control panels. If your ship has an antenna, you can tick that box and the block will show up. Handy dandy!

To add to that you could also use the programming block to identify everything, though it'll utterly root your ship's naming. Assuming this is creative, drop this into the code of a programming block, set ownership of everything to "Me", then execute:

void Main()
{
    for (int idx = 0; idx < GridTerminalSystem.Blocks.Count; idx++)
    {
        IMyTerminalBlock Block = GridTerminalSystem.Blocks[idx];

        Block.SetCustomName(String.Format("{0} ({1},{2},{3})",
            Block.DefinitionDisplayNameText,
            Block.Position.AxisValue(VRageMath.Base6Directions.Axis.LeftRight),
            Block.Position.AxisValue(VRageMath.Base6Directions.Axis.UpDown),
            Block.Position.AxisValue(VRageMath.Base6Directions.Axis.ForwardBackward)
        ));
    }
}

It'll change things to the block's display name (the default) followed by local grid coordinates. (e.g. "Programmable block (4,3,1)" or "Small Reactor (2,3,5)"). You can then also turn on/off the HUD display as needed to align yourself, but after you get the gist of where x/y/z run within your local grid you should be good with just using that ;)
