Another Gmail bonus. Not that I have super long labels.
Gmail Now Lets You Make Longer Labels (Without Wasting Screen Space) [In Brief]: "
Up until today, you could only make new Gmail labels that were 40 characters long—which could sometimes prove difficult. They've now extended that limit to 225 characters, giving you a lot more leeway in how you organize your messages. They've also truncated the actual labels themselves in your inbox, so they don't take up too much space if they're long or buried in a long trail of nested folders (mousing over them, however, will show you the full label name or path). It's just a few small changes, but certainly welcome ones for label addicts. [Official Gmail Blog] More »"
