Maven-related. I'd really appreciate the following improvement. Today the best granularity one can get with this action is module-level. Still not very usable for a complex dependency graph - takes several minutes at times to process *every* dependency.
IDEA already has an understanding of maven dependencies for a module (those Libraries/Maven: *). What would really boost productivity, especially when working with a foreign/new codebase is ability to right-click the library and invoke download of source/javadocs for *this library only*. I know maven doesn't do that, but as mentioned above there's nothing preventing IDEA from doing that, all the pieces needed are there.
