i forgot to mention that overnetclc had a confirmation dialog for removing downloading files
every files in download list was labeled with a number when displayed with 'vd' command (corresponding to 'show dl' in amulecmd)
amulecmd$ download rm 1
...are you sure you want to remove files 'some_name.some_extension' from you download list?(yes/NO)
in a download list with 5 files, removing file #3 implied that file #4 became #3 and #5 became #4, i think downloading files were sorted about priority at default
so if you wanted to remove many files subsequently, you needed to check every time the number in the download list
