Rename Entries to Content on CP top menu A purely cosmetic change, but just wanted to know if its possible to change the menu item for Entries to something like Content? From a client point of view, I just know some will beg me to change this :)

Would also be handy to remove the Dashboard altogether as well for some cases.
For custom "cosmetic" changes on the Control Panel there's these two Plugins by Lindsey DiLoreto:


Control Panel JS
Control Panel CSS


.

You can do both, hiding and renaming of menu items with CSS:

#nav-dashboard {
  display: none;
}

#nav-entries a,
#nav-entries a:hover,
#nav-entries a:active {
  color: transparent;
  word-spacing: -9999px;
  letter-spacing: -9999px;
}

#nav-entries a:after {
  content: "Content";
  color: #d7d9db;
  word-spacing: normal;
  letter-spacing: normal; 
}

#nav-entries a:hover:after,
#nav-entries a:active:after {
  color: #fff;
}
