I have a suggestion for the F8 menu (Edit textures on already built blocks): Will there be any way to edit besides the textures... The scale of these? In addition to giving us the data on the scale sizes in those already built blocks?
With F8 if you bring up the menu and then the change texture, right click on the texture preview on the right and it gives you the option to change the scale. It'll show what the default scale of the block is.
