When I use the long editor, I can use the Tab key to push text into vertically-aligned locations. In other words, Tabs are interpreted as tab-to-tabstop-location. However, when I finish editing and look at the node, Tabs are interpreted as simply a long white space, so columns are no longer vertically aligned. The attached screen-snipped image illustrates this. Using v0.9.0 on Windows 7/Pro 64.
