I'm proposing we have a few more key blocks added to Creative, I'm guessing you (The Admins) might already be planning to add some more, But a few key blocks I'd like to see in Creative are:
Sand/Sandstone (Used alot for skin pixels in a lot of sprites)
Wood/All Logs/Planks (also used for skin and shading)
Dirt (Used for another shade of brown)
Ice? (not sure about this one, but i'm sure some people could use this in a project)
Clay (Different type of gray)
Cleanstone (More gray shades)
SoulSand (More Brown)
If there are any more blocks that you think should be added to Creative, post below.
