I just moved a thread from User_talk:A to User_talk:B and Special:Log displayed the following entry: # hh:mm, data User moved Thread:Name to Thread:Name (reason)
As the thread was moved from one page to the other, I would expect those pages to be mentioned in the log, and the entry to be something like "moved Thread:Name from PageA to PageB".
Version: unspecified
Severity: enhancement
