The 2 checkboxes "name" and "extension" are useless.
Wether one or another or the both are checked or unchecked, it is allways the name that is applied to any of the modifications.
N.B.: This issue is about version 0.6.The problem doesn't show up in the version 0.5
Thanks, this has been fixed. I simply re-uploaded the same sources file without making another release. It may take some time before all mirrors are updated.
