Simple app showing what I need to see. The only requests are - Something on the memory tab to show small indicators for gigs used - Something on the CPU use (25, 50, 75, 100) to quickly see rather than guess. - For long text a toggle to show/hide the details.

No doubt it's a great app for Chromebook, it shows most of the stuff in one place. The one thing that i missed here is internal storage. That should also be mentioned here. Also in network section, it should mention that if the device support Bluetooth, Lan, Wifi with yes no kind of table that will become a great plus.
