WhatsApp now supports Apple's 3D Touch

After an update for iOS users, the well-known, popular Messenger now supports the new feature, this also the brand new one iPhone 6S owns: 3D Touch. It is now possible to switch directly to a new chat from the home screen and search for messages.
WhatsApp has also integrated the new 3D Touch feature into its app. This is because every programmer has to adapt their app specifically for the new feature in order to be able to use it. 3D Touch is not supported by every device: it is currently only installed in the new iPhone 6S & iPhone 6S Plus with iOS9. Depending on the pressure, you can now "right-click" on supported apps, just like on a PC, to get more detailed information about the app, to directly execute a specific function of an app, such as opening the search function, or to open a specific post.
A small preview for business cards and pictures
If you hold down longer and firmly on a business card or on a picture that was sent to you in the chat, you will now see a small preview of the respective contact or information about the picture. Furthermore, a small innovation has been introduced: now it is possible, as with Android, to reply to the message directly with a message line through a popup window in WhatsApp, without having to open WhatsApp.
WhatsApp's 3D touch features are currently still expandable, but are some new steps into the future of 3D touch.
Very cool feature! Unfortunately, I don't own an iPhone myself: / I currently have a Samsung Galaxy S5.
