The default implementation is to show spring elements in workspace or on current file. It would be really usefull if the elements can be filtered on the current project as well. One could easily filter the elements by their path using the current active editor's project name. This can be programmed to another cycle of CTRL+6 like workspace, project and current file. Or else one could program it to be able filter using a different keyword in the filter field. I personally prefer the option 1 since it make the user experience more straight forward.
