When we are using file-roller, geny, gimp or other gtk-program, it is often need sort files in different ways. We can sort by filename, date of modify, size, but the sort by filetype is missing. So, for example, if we have many files with same names but different extensions, and we want to add in archive (via file-roller) only .jpeg but not .png we must look all files in catalog and add only needed files. If we will have this option we can easily select needed files via SHIFT+DOWNARROW, as in qt-based programs.
