Being off-subs I am not able to participate in anything 'ideas' related so have had to make this separate post
I love this suggestion by Dan The ability to modify Global Variables without opening the Equation manager and I hope it gets picked up.
I have however just accidentally discovered a way of modifying global variables outside of equations, in the Modify Dimension Dialog.
You can 'toggle' from this
and then the global var is editable right there!
Not as nice as Dan's suggestion, but good to know perhaps.
