IntelliJ: Working on multiple projects

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.

I am modifying codes of all A/B/C projects, (A is MVC app, B are business services and C is some shared layer).

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 n instances) of IntelliJ IDEA.

Am I missing something? Is there better approach when using IntelliJ? This is the biggest downside of IntelliJ for me atm.

I think this has improved with recent versions of IntelliJ. In my current version (12.0.2), you can add any number of separate Maven projects to the same "workspace".

The simplest way I've found to do this is to click the little + icon in the "Maven Projects" window (View > Tool Windows > Maven Projects) and then select the additional pom file you want to import.

Step 1: Open "Maven Projects"

Step 2: Select the project you want to import:
