Locked or missing files

ubuntu 14.04
LO Version: 4.2.8.2 Build ID: 420m0(Build:2)

I get a lot of system crashes for a variety of reasons. That means, I'm constantly recovering files when I re-open LibreOffice. Some of those files are /tmp files (example: attachments opened while I'm in Thunderbird), which get deleted when the system reboots. When I restart LO, it tries to recover those /tmp files which of course are gone forever. How can I tell LO to stop trying to recover those files and permanently stop tracking them?

Also, similar problem - I have a locked file. While I can manipulate it through the file system (mv locked file to save file, etc.) it would certainly be nice if there were a way to force an unlock through LO. Is that a feature or does it need to be added?

Thank you

If you update at least to the 4.3 branch you will have the option to remove
any document from the recent list (I would recommend 4.4.7 which is the last
release in the 4.x tree)
If you want to stick with 4.2 you can use the History Master extension
http://extensions.openoffice.org/en/project/history-master
After installing, close LibreOffice, reopen, click on Tools > Add-Ons >
History Master > Remove inaccessible items

Notice that documents in currently disconnected drives (such as an external
HDD) will also be removed.

I believe such an option would be useful (an "Unlock document" button). Can
you add an Enhancement request in https://bugs.documentfoundation.org ?

I also use Thunderbird under Windows 7 Pro. Re-opening LibreOffice (at least
with version 5.1.3.2) after Thunderbird as been closed (and the tmps have
been removed by Thunderbird on exit) doesn't show any temporary files in the
Recent list or in the Start Center.

I have no idea in which version this feature was added/fixed but it is
currently not an issue (at least under Windows)
