After years of using notepad++ for web development I've decided to start using some IDE. I've tried both: Zend Studio and Eclipse PDT. It appears they are pretty much similar.
When working on multiple projects I used to make "sessions" in notepad++ to keep each project files opened in editor. How do I achieve that in Zend Studio or Eclipse PDT? I mean when switching the project, I want one set of files to be closed in editor and another one to be opened.
