Gmail 4.3 recently hit the streets, bringing with it a long-awaited (by me, at least) ability to archive email directly from the notification panel. It's awesome. But what else did Google sneak into our phones and tablets with this update? Let's find out.
Fair warning: this is going to be one of those teardown sessions that raises more questions than answers, so bring your speculation hat.
Gmail has always had this wacky file in it called "experimental_preferences.xml." I've mostly ignored it, because it has only ever had two relatively-boring things in it: "full text search," which works already; and "Enable drag and drop contact chip," which would let you type a name into the "To:" field and move it to something like "CC:" by dragging it.
