Still no update on this feature? This was my main reason for installing, I assumed it would be able to sync files across ALL devices, not just back and forth between pc and phone.
The example of this would be transfer to desktop to work more comfortably when i get home, or reverse when I'm going on a trip.. sending pictures to one pc for backup, etc.. If it can send directly over the local network, without need for airdroid to host any content, I see no reason not to include this feature.
Another use might be to reply to a text regardless which system I'm on at the time, instead of having to sign in at the beginning of my session every time if I switch devices, which is tedious and takes away a lot of the benefit. Pushbullet had this feature over a year ago and no longer is in active development, so i hoped I could fully replace it with AirDroid.. but it seems not. Some people like myself have workstations or gaming desktops as well as laptops, this would bridge those gaps and make the program much more convenient and useful.
