This is probably more of a mobile feature, versus PC - but I'd like to see enhanced application monitoring features. I'd like to see an "Application Log" that includes which applications are being accessed and the duration of access. Something with a log along these lines:
21:27 YouTube 1min
21:11 Instagram 1min
20:58 Facebook 4min
The log could include the timestamp of access, the name of the application, and the duration of use.
