Icons were decreased in sized and placed in row with their labels.
'Enable power management' was moved to bottom. Suppression messages
kept on top, but now mirror in the checkbox's tooltip too.
The complete main view can scroll now (only batteries could scroll).
For the 'Enable power management' checkbox, fixed tooltip and switch
area (tooltip was only on text, and switch was on full width).
Issues:
Tab does not cycle though when on desktop (shift-tab works).
