-Gisquick User Interface (UI) is designed to be simple,
-self-explanatory, and responsive. The major part is occupied of *map
-canvas* (``1``). On the left is located :ref:`content menu
-<content-menu>` (``2``) which is possible to hide by button on its
-right side (``3``). Corners of map canvas are filled by (from
-left-bottom corner, clockwise) by *map scale* (``4``), :ref:`tools
-menu <tool-menu>` (``5``), :ref:`user menu <user-menu>` (``6``) and
-:ref:`zoom menu <zoom-menu>` (``7``). In the bottom part is located
-statusbar showing current scale, projection and map coordinates of the
-cursor (``8``).

-The main idea is, that once print is activated in Gisquick, it will
-download raw print output from QGIS Server using GetPrint request and
-will allow interactive visualization of map content directly in this
-template.  One can zoom, pan and rotate map and see exactly how the
-result will look like.  To get the better idea, see video below.
