Need more options
[x] don't try to thumbnail/summary content on optical drives unless asked.
[x] likewise network drives

[x] don't obey any drag &drop command which took less than 0.4 second to execute
[x] don't do 'undo' without asking if ok, if the action being undone was more than 20 seconds ago.

[x] don't claim that filenames like ".foo" are not allowed.
