• Yes. The best thing to do if you decide you want to use a module that you have already removed, is to 'unhide' or show the module again. 

• You can do this easily by clicking on the 'include removed modules' button at the bottom of the module section in the editor. 

• Hidden modules will have a white 'Show' button. Just select the module you previously hid and click 'Show' to make it reappear.
