Every once in a while, you have a new and fresh install of Kali. The one thing what’s bothering me, is the small Gnome menu. Because it’s so small, you can’t always tell what you’re starting up.
To make it all a little bit more clear, edit the following file:
/usr/share/gnome-shell/extensions/apps-menu@gnome-shell-extensions.gcampax.github.com/extension.js
Search for:
this.categoriesBox.box.width = 300;
and replace it with:
this.mainBox.box.width = 950;
this.categoriesBox.box.width = 500;
Log off and logon again, the menu will be a lot wider. You can tweak the values to your own needs.
