It doesn't really matter. If you have access to your command window, you can open the same window by typing SET. Beware, though, that when reactivating that window, the list on the left will not refresh every time you click on it (like it did forever), that when you open a table it's not necessarily selected (like it did forever) and a few more little annoyances.
