Wouldn't it be great, if you had a handy GUI that automatically switches all bricks with a certain color to another color?
It would only be available for admins on server though.
Example.
Imagine you have a build, like the one in
THIS topic. But you decided that you wanted to change the white bricks to black, and the black bricks to white. You would open up the GUI, it would detect the bricks with the different colors on the server. You select the color that represents the brick you want to change. Pick a new color, in this case, black for the current white. Press modify, and BAM! All of the bricks that where once white, become black!
Is it even possible?
