Often I have the case that I have a file opened in the tabs like item_category.xml here:

The project explorer still shows something else. Any way to open the path to item_category.xml in the project explorer? I already checked the right-click menu of item_category.xml, but couldn't find a matching option.
Use that symbol in the project explorer (shortcut:
Alt+F1,1):More information on the feature: Locate a file in the Project tool window.
