I am guessing you don't mean that Gmail hasn't really progressed in many years now. Sure, they've bolted on features and functionality, but they have also probably intentionally delayed or been distracted from adding real value because e.g., it would have competed or distracted from other projects like G+ by, e.g., improving the contacts view, which is really rather unusable. Another issue that bothers the hell out of me is that with all the scanning of emails they do they can't figure out a probably date and time from emails that were turned into events, which mention a date and time in the body or subject. Something I also find rather annoying is that you can't filter messages only to me from a specific sender but without any other recipients.
