Text Variables needs a dockable window/panel/pod. Pull defining new variables out of the Text menu and put it in a panel that we can access without having to drill down through the UI.

Having Text Variables available in a panel in this fashion would let us place the cursor, double-click to add a variable, move the cursor via arrows and double-click the next variable. We would also be able to click several variable in a row without having the laboriously drill down through the UI to get to the list. This is very frustrating when you have several dozen variables that need to be placed.

Even making the Text Variable definition window non-modal would be an improvement, but seeing the list broken out into its own panel would be a huge improvement.

Oh, and let variables break across lines. Duh, right?
