Currently the ofbiz-component.xml in themes refers to 2 webapps common-theme and images. The location of the former is location="webapp/common". At least on my machine this creates, or has created, a local only common directory under themes At some points (some months ago IIRW) I had to add a bunch of .gitgnore files unders subdirs of this local only common directory.
I think it's better to have the location of the common-theme webapp at webapp/common-theme. Hence the possible local only common directory under themes disappears. Backend and frontend work fine. It's just some rename so should be easy to revert if ever I miss something.
