Responsive Design

[imhemish]

While linux phones are being developed, the apps on these phones are the same as of desktops. The solution is to make responsive apps. While this app does not automatically resize itself on smaller window/screen sizes, one can just rearrange the panels to fit all the panels, but this has one problem, all panels fit nicely, but the headerbar is too wide, and it loses buttons when resized, this should be taken care.
It also helps on tiling window managers, as this app would behave nicely in a tiled window
