So I just moved from Eclipse to IntelliJ after doing some research. The only thing that I miss is that in Eclipse I can have multiple projects in different tabs and compare proj
Using Maven: a untested aproach could be to have a simple maven Project including the other Maven projects as its childs and then import the simple maven Project that only defines the others as childs (and yes - please vote for such standard features).
There is a workaround solution. Please see here:
IntelliJ: Working on multiple projects
I'm doing the same. It worked for me really, but I get the dialog asking me for removing the imported modules because they are not in the maven structure.
Also trying to solve this.
No, it's not possible. Please vote for this feature request. Note that you can add your multiple projects as modules to Intellij Idea project to be able to view them in a single frame. BTW, there is a document intended to help users migrating from Eclipse to Idea - see this FAQ - you may find it helpful
