In Eclipse IDE, I find it very inconvenient to go to the the Window:Open Perspective or Window:Show View submenu, and then select the one I want in dialog that is shown. I was inconvenienced enough that I wrote a simple Eclipse Plug-in called - Perspectives and Views Toolbar. The basic idea is that it adds two drop down menus to the toolbar. Using the drop down you can directly select the Perspective or the View that you want to show.
