This option is no longer available. Can we have it back please.

File delete method
Select the way you want to delete files. Options are:
1. Confirm Delete
2. Confirm Delete/Trash
3. Confirm Trash
4. Direct to Trash

You must be using Windows.
From the news page:
• removed support for sending removed transfer files to trash on Windows version due to bad fallback behavior in API

It would still be a nice feature to have back. Windows or otherwise. If there's a bug, time for a fix.
