Drag&Drop for any kind of file is very easy to implement.
Try to rebuild the desktop after erasing de "old" (1.0) version.
I don't think so. It would be a good idea, if you send me (PM) one of those UTF-8 files you are having troubles with. To testing purposes.
I have some little succesful in writing UTF-8 files. But I still have a lot of work to do to fully support UTF-8 (if some day achive that).
Thanks, Those things will be interesting once UTF-8 were working.
