When the user tries to "Drop the Development path", the files which are available in "Head level of specific variant" is not registered anywhere. Which means when the user drops the development path, he have no option to know what are the "head revision files".
My idea is, when "Drop Development Path" option is invoked, a "Checkpoint" needs to be created with current "member revision of files" (as similar to restore subproject happens). So if suppose they need to know what are the revision which I currently worked on specific "Variant" they could view easily.
