title: SQL Developer won't show the connections Tab
body: <p>So SQL Developer won't show the connections tab no matter what I do. 
  I've tried going through the "view" tab and clicking into the "connections" and I've also tried clicking the new button. I've also tried an uninstall/reinstall, but nothing.</p>
  
  <p>It's probably something simple, but I'm fairly new to it, can anyone direct me or provide any advice? 
  Any help is really appreciated :) </p>
