Microsoft always adds some nice hidden features with most builds for the Windows 10 Mobile Insider Preview. The company added a pretty sweet feature with the latest release for the Windows 10 Mobile Insider Preview (build 10549), too. Microsoft now shows more info about devices connected to your Mobile Hotspot when other devices connect to your Mobile Hotspot. The Mobile Hotspot page now provides the network address, and the physical address (MAC) on the Mobile Hotspot page, which is quite handy.
If you want to check out this new addition by yourself, head over to Settings > Network & Wireless > Mobile hotspot and enable mobile hotspot. Also, if you use hotspot quite a lot, tell us what you think of this new feature in Windows 10 Mobile in the comment section below.
