It would be great if the variables panel had a better interface. I would love the ability to reorder variables so that variables that control a certain panel are grouped. Currently I have to plan all variables first to make sure the order is correct which doesn't allow for very agile design practices.
It would also be great if the "Name" column was longer or could be changed by the user by dragging because longer variable names tend to look the same unless you hover to grab the tooltip.
I attached an image of the problem I'm seeing. There is a variable for each corner of a button, but you can't see which one you are editing.
