As bad as I originally thought Gmail's new interface is, it's worse. They have hidden the 'choose font' button behind a T. Sure, T stands for font. I get it. This is what it looks like:
This is just more evidence that Google's new interfaces for Docs, Gmail, etc., are not well thought-out and are simply change for the sake of change. Overall, replacing words with obscure pictographs and then using letters that have no apparent relation to their function are slaps in the faces the user community.
