One of my biggest disappointments with Gnumeric is the file extension: tab completion only works sometimes, and I'd really like to change find ~ -name \.gnumeric to find ~ -name \.gnm or find ~ -name \*.gsc Also it takes up more space when listing files in a terminal. Also, the 3 letter convention is a somewhat helpful limitation in the same way that countries defining which side of the road to use is actually helpful. For instance, it is nice to have all of my JPEGs ending in .jpg rather than a mix of .jpg, .jpeg, .JPG .JPEG.
