Hovering the mouse pointer over a tab in the Explorer Panel should show a tip that contains the full path of the folder.
I could be in sub-folder ABC of project WXY in one tab, and sub-folder ABC of project XYZ in another tab.  The tab just shows "ABC".  But what project folder is it?  I don't know so I have to click on it so the full path shows up in the Path window.  Instead, a tip should pop up that shows "D:\Proj\WXY\lvl1\lvl2\ABC"
