Maybe I should add this as a Feature Request? It seems there is no way to scroll to the right to add/view components that I add to the Subcomponents tab that are off-screen to the right. In order to see them, I have to move the Projucer window partly off-screen to the left, then drag the window size to the right to expose those controls again. It would be nice if there were a scrollbar for when the UI component is wider than the space provided.
