When it's not quietly compiling your phone number and the phone numbers of all your friends, the Facebook Messenger app is pretty darn useful.
It is a very powerful communication application: From one place, you can now contact anyone in your phone book or your Facebook Friend List. It's compact and convenient, and you don't have to go through the hassle of granting the app permission to access your Facebook (because, well, the app is Facebook). In my experience, Facebook Messenger loads just as quickly as my text messages do, and the ability to instantly reach all of my contacts on their phones--whether I have their phone number or not--makes Messenger extremely useful.
There are, however, several features that are noticeably (in some cases inconceivably) missing that make Facebook Messenger a bit of a hassle to do certain things. Here are the changes I hope Zuck and the team push through for Facebook Messenger 2.0. Want to know more about how to use the app?
