Oh, I see, the names in the returned object. That's intentional.
As dara frames cannot have unnamed columns in R objects, I thought
you meant unnamed in the data editor.

I have already said there is a problem with that pre-version that the
double-click interval is set wrongly, so it normally thinks you have
double-clicked before selecting the cell. The problem is the clicking, not
being a data frame.
I'll put up a new version in a day or two. Already there are lots of
extra features, for example variable-width (and re-sizeable) columns.
