Yes, for sure, the size of the postcards is small and sometimes it is impossible to drag the material from small parts from the postcard.
And why now I can not see the names of the postcards (earlier in Artlantis 4 were the names of each postcard)?
Without the name of postcards for example it is not clear what material on the card is located.
P.S. And another question on Shaders is why I can not save your Shaders when there are no textures on it (it consists of one material).
I want to correct the standard Shaders (gold, copper, glass, etc.) to get more realistic materials, and it's impossible to save when there is not one texture on it...
