WhatsApp seems to be preparing a new dedicated application of its messaging for Windows 10
Before going further, it seems necessary to specify that there is already a WhatsApp official application for Windows 10. But far from being a version specific to Windows 10, this one is only a simple porting the web version. And the Windows Phone version - also still regularly updated - does not use the universal UWP standard. But it seems that WhatsApp is preparing a much new version of its application.
The Windows Central site (link in English) has apparently fallen on design boards of a possible new WhatsApp application using this famous standard "universal Windows platform application" (or UWP), which has the particular advantage of to be usable on all devices using Windows 10. And unlike the current application, different icons on the models suggest that functions how sending voice messages, photo and audio and video calls would finally be integrated in the desktop version.
And although it would obviously still link the desktop application to the mobile application with a QR code, this is still very good news for all Whatsapp users. Note that many of the models have a vertical format. If it is possible that it is simply a resized window, it also suggests a use in tablet mode on the Surface .. or even smartphone use on the hypothetical Surface Phone.
