Danilo Celic of Community MX has released an excellent extension that enhances code view of Dreamweaver -- the CMX Current Column extension. It shows the current column under your cursor as you are typing in code view. If you have Homesite of CF Studio, this feature was included, but DW has no other way to retrieve this information.

The extension is free for members with a small fee attached for non-members: http://www.communitymx.com/abstract.cfm?cid=3F8FC
