Fully qualified class/interface names in "All classes" frame would help distinguishing equally named ones from different packages.

N/A

Fully qualifying the name would clutter the narrow column for those 2 or 3 out of 1500 classes in the JDK.  The cleaner solution is to add tooltips to the class name, so when someone hovers the mouse over the name, the fully qualified name would appear.  Definitely worth doing.

After trying this, it seems unnecessary to display the class name in the tool 
tip.  Including just the package name is sufficient, and perhaps preferable,
as some class names can be very long, and the dot separator for inner 
classes can confuse where the package name ends.

A closely related RFE 4714257 "Add description that italics means interface for accessibility" has the same solution, except adds the word "class" or "interface".

I am closing this request as this was fixed by 4714257, described above.

This feature should also display the fully qualified 
physical path of the file.
