Love the Magic Sheets,
Just a couple of items I would like to see:
A> If I Move a Pallet to a Different Number, Have it Update any Target Id's that Reference it.
B> To the Color Menu, Add a way that when a Fixture(s) is selected, It "Highlights" the button if the Fixture has parameters in the palette.
C> Add a "Table" Box that can display Custom Q-list / live table / Color List / etc....
D> add a tool, such as photoshop's eyedropper, to quickly copy Color/Size/? Attributes from one object to others without disturbing the target/id.
E> With the Tab Object, Make the bottom Border Optional. That would make it easier to build a "Folder", instead of using another rectangle to Hide a section of the border.
