Provide the ability to close and re-open modules in multi-module projects without going to the project dialog. A closed module would not "exist" in the project except for a single closed-module node in the project tree. This change would make idea behave similarly to eclipse in this regard. Alternatively, maybe you create a node at the bottom-end of the project tree to keep "closed" modules so that open projects always bubble to the top of the tree. This might be a better closed module behaviour than eclipse's. Justification: I find that I deal with a large number of web app modules and often times they have enough similar code that if need to search for something or whatever I want all but the module I am dealing with to disappear. However I want to (and do) keep all these modules in the same project and therefore find myself fairly frequently removing modules from the project or finding a module to re-open from its on disk location. This change to the UI would save me a tedious open/close module work flow. I could not find anybody asking for this but I would be a bit surprised if this is not a duplicate request. thanks,
