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"
