Hi Horia Alin,
we actually do that. If you enable Wifi manually, we won't disable it until the profile is switched to some other profile.
Have you tried the latest version 1.2.1057? Because in the older one (1.1.1001), we'd still respect the "synchronization period", which is in "Advanced settings" of each profile. That means that if you had set it to 15 minutes, we'd still turn the internet completely off when you turned the screen off (and turn it on periodically each 15 minutes), and then turn it back on (with Wifi, though) when the screen got back off.
What we do now is when you override the profile setting by turning Wifi on manually, we ignore the sync period setting and just keep the internet on all the time.
