QGIS is highly configurable through the Settings menu. Choose between Panels, Toolbars, Project properties, Options and Customization.
In the Panels‣ menu you can switch on and off QGIS widgets. The Toolbars‣ menu provides the possibility to switch on and off icon groups in the QGIS toolbar (see figure_panels_toolbars).
Figure Panels and Toolbars:

Activating the QGIS Overview
In QGIS you can use an overview panel that provides a full extent view of layers added to it. It can be selected under the menu Settings ‣ Panels. Within the view is a rectangle showing the current map extent. This allows you to quickly determine which area of the map you are currently viewing. Note that labels are not rendered to the map overview even if the layers in the map overview have been set up for labeling. If you click and drag the red rectangle in the overview that shows your current extent, the main map view will update accordingly.

Show Log Messages
Since QGIS 1.8 it’s possible to track the QGIS messages. You can activate
Log Messages in the menu
Settings ‣ Panels and follow the messages
in the General and Plugin tab during loading and operation.
In the properties window for the project under Settings ‣
Project Properties or
Settings ‣
Project Properties you set project specific options. These
include:
Some basic options for QGIS can be selected using the
Options dialog. Select the menu option Settings ‣
Options. The tabs where you can optimize your
options are:
GDAL is a data exchange library for raster files. In this tab you can define which GDAL driver to be used for a raster format as in some cases more than one GDAL driver is available.
Additionally you can define whether to save the path for svg textures absolute or relative in the General tab of the Settings ‣ Project Properties menu.
The next 3 options refer to the Offset Curve tool in Advanced digitizing.
Through the various settings, it is possible to influence the shape of the line offset. These options are
possible from GEOS 3.3 .
The CRS tab is divided in two areas. The first area allows to define the default CRS for new projects.
The second area allows to define the action, when a new layer is created, or when a layer without CRS is loaded.
Figure Network Tab:
Excluding some URLs can be added to the text box below the proxy-settings (see Figure_Network_Tab) by pressing the [Add] button. After that double-click into the just created URL-field and enter the URL you would like to exclude from using the proxy. Obviously the button [Remove] removes the selected entry.
If you need more detailed information about the different proxy-settings, please refer to the manual of the underlying QT-library-documentation at http://doc.trolltech.com/4.5/qnetworkproxy.html#ProxyType-enum.

Using Proxies
Using proxies can sometimes be tricky. It is useful to ‘trial and error’ the above proxy types and check if they succeed in your case.
You can modify the options according to your needs. Some of the changes may require a restart of QGIS before they will be effective.
\HKEY\CURRENT_USER\Software\QuantumGIS\qgis
The customization tool is a new development in QGIS 1.8.. It lets you (de)activate almost every element in the QGIS user interface. This can get very useful if you have a lot of plug-ins installed that you never use and that are filling your screen.
Figure Customization 1:
QGIS Customization is divided into five groups. In Docks you
find the dock windows. Dock windows are applications that can be started and used as
a floating, top-level window or embedded to the QGIS main window as a docked widget
(see also Panels and Toolbars). In
Menus you
can hide entries in the Menu bar. In the
Status Bar features
like the coordinate information can be daectivated. In
Toolbars
you can (de)activate the toolbar icons of QGIS and in
Widgets
you can (de)activate dialogs as well as their buttons.
With Switch to catching widgets in main application
you can click on elements in QGIS you want to be hidden and find the corresponding entry
in Customization (see figure_customization). You can also save your various different
setups for different use cases as well. Before your changes are applied, you need to
restart QGIS.
