title: IntelliJ: Working on multiple projects
body: <p>We build in maven multiple projects (let's name them A,B,C). Project A uses .jar of project B which uses .jar of project C.</p>
  
  <p>I am modifying codes of all A/B/C projects, (A is MVC app, B are business services and C is some shared layer).</p>
  
  <p>The thing is, in Eclipse/NetBeans I can see all of them at once and it's comfortable to modify them. In IDEA though, I have to open 3 instances (or <em>n</em> instances) of IntelliJ IDEA.</p>
  
  <p>Am I missing something? Is there better approach when using IntelliJ? This is the biggest downside of IntelliJ for me atm.</p>
