definitely! this would be a huge enhacement. wouldn't it be almost enough to 
limit all column types to be the same? this could be visualized by 
deactivating/greying out all of the "type" row except for the first cell (of 
course there's some more changes needed internally, to then actually write a 
matrix()).

at a later point, it would be nice if you could seamlessly turn matrices into 
data.frames and vice versa, perhaps in the context menu you get when right-
clicking on the data.frame (e.g., after "enable editing"). visually, this 
could toggle the greyed-out type row.

if the special case of one column was suported, you could also use this to 
edit vectors just the same :-)
