Things I like from ver 3 that are not in ver 5:
Add the option to automatically cleanup the download list when the download is complete.
Select your own extension on downloads that are busy.
Option to always preallocate disk space for any file size.
Ability to make windows size even smaller.

I am using FDM ver 5.1 after using ver 3 for many years. In ver 3 it was possible to set it up that the download list clears after a successful dowanload. Can this be done in ver 5.1?
