Without knowing i can almost guarantee that every single content creator in this community thought at least once that the skin pattern of a block did not mesh well with their ship design.
Examples:
Windows not lignign up with the rest of the hull design or being cut in half
Revealed energy blocks with details that are either too small or too big for the rest of the ship
Most block patterns are simply terrible in small scale ships so until you get to xanion you'll have a front seat view to massive window, or smashed armor.
When building a pattern using blocks you will probably jeopardize structure just to make them fit properly, which shouldnt be required since the blocks are already there, they just mismatch.
So here's the idea: Make block skins draggable and scalable. You select a block, and turn on the tool with a button, then you become able to drag around the skin of said block or scale it with the mouse wheel.
Smaller ships will get to enjoy the textures of every block instead of cover everything in armor just because they look awesomely terrible.
Larger ships will get more design options to play around with since you can make details larger
More possible details with existing game assets.
