wanted software feature

– more space for the name of an attached file, when sending an email.
Sometimes the names of related files are distinguished only by their trailing characters, and so it would be nice to have more space given for the name of an attached file. (Sure, you can always click on the file name to see it in its entirety, but it would be nice to have at-a-glance functionality as well.) By all appearances such space, immediately to the right of the currently used space, is available.
