The little things in an interface

You know that you’re making good software when you obsess over a 1 pixel abnormality:

Table headers are one of those things we have wanted to ‘fix’ for a long time, but somehow never got around to earlier.  By default, table views in Cocoa apps show a little separator on the right-hand side of every column header, even in the rightmost one when theres a scrollbar under it.  It has always bugged me to no end that in this situation, that rightmost 1px gray line – which, by the way, is completely unneeded – is exactly one pixel off to the left compared to the scrollbar drawn below it.
