 ===== Menus =====
-/usr/share/applications/
+On Debian XFCE the most common locations for storing .desktop entries are:
+  * /usr/share/applications/
+  * ~/.local/share/applications
+  * /usr/local/share/applications
+===== Themes =====
+In Debian with XFCE, theme files for the graphical interface are stored in system-wide locations.
+=== System-Wide Themes ===
+    GTK Themes: /usr/share/themes
+    Icon Themes: /usr/share/icons
+    Window Manager (xfwm4) Themes: /usr/share/themes
+=== Per-User Themes ===
+    GTK Themes [modern]: ~/.local/share/themes
+    GTK Themes [legacy]: ~/.themes
+    Icon Themes: ~/.local/share/icons or ~/.icons
+    Window Manager (xfwm4) Themes: ~/.local/share/themes/
+==== How to Install a New Theme ====
+Download: the theme file from a source like xfce-look.org. Extract: the theme's downloaded archive.
+Copy: the extracted theme folder (which contains folders like gtk-3.0 for GTK themes or xfwm4 for window manager themes) into one of the user-specific directories mentioned above, such as ~/.local/share/themes/ for GTK/window themes or ~/.local/share/icons/ for icon themes.
+Select: the new theme by opening Menu > Settings > Appearance and choosing your theme from the Style or Icons tabs.
+==== Theme per application ====
+Select an explicit theme for an application:
+  env GTK_THEME=Adwaita:dark simple-scan
+  env GTK_THEME=Nordic-darker simple-scan
+  env GTK_THEME=Shades-of-gray-Orange simple-scan
+  env GTK2_RC_FILES="/usr/share/themes/Ambiance/gtk-2.0/gtkrc" firefox
+Newer versions of firefox use GTK3. Another way to overrule default thema from within Firefox:
+  In Firefox URL bar enter about:config.
+. Create new String value with name widget.content.gtk-theme-override (Right click > new > String)
+. Set value to Adwaita:light (if your distribution does not use GNOME desktop, you should use a name of light GTK theme which is installed on your PC)
+. Restart browser
+===== Lightdm Login Styling =====
+Login page is created by lightdm. Modify styling by doing:
+<code>
+# nano /etc/lightdm/lightdm-gtk-greeter.conf
+--------------------------------------------
+Modify the following lines:
+theme-name=Adwaita-dark
+font-name=Sans Regular 11
+xft-antialias=true
+</code>
+===== Desktop Icon Spacing =====
+To change the icon appearance on the desktop, to:
+ - Show multi line icon text labels
+ - Reduce the space between icon image and text
+ - Change the distance between icons
+Edit the `gtk-3.0/gtk.css` file of the theme and add the following lines:
+```
+$ nano /.local/share/themes/Shades-of-gray-Orange/gtk-3.0/gtk.css
+-----------------------------------------------------------------
+XfdesktopIconView.view {
+    -XfdesktopIconView-ellipsize-icon-labels: 0;    	/* Allow multi-line text wrapping without truncation */
+    -XfdesktopIconView-cell-padding: -4;    			/* Keep cell padding non-negative so bounding boxes do not bleed */
+    -XfdesktopIconView-cell-text-width-proportion: 2.5; /* Tighten vertical space specifically between the icon image and the text label */
+}
+XfdesktopIconView.view .label {
+    background: transparent;
+}
+```
+To restart the XFCE, execute:
+```
+$ pkill xfdesktop && xfdesktop &
+```
+===== XFCE Debugger / Inspector =====
+To start inspector window:
+```
+$ pkill xfdesktop && GTK_DEBUG=interactive xfdesktop
+```
