I use the History Master Add-in:
because it offers vastly superior file list handling for my purposes (it should really be built in to Libre Office in an enhanced form) - it allows the recent file list to be expanded to 100 files, and for some management of the files displayed in the drop down list, including ordering, purging of unwanted and deleted files from the file list, display only of files of the same type as the component you are working in (e.g. just spreadsheets, or just presentations etc.)
It no longer works with 18.104.22.168, with the menu under Tools - Addon - History Master to set its parameters and manage lists, and the File - Recent Documents of Same Type options both producing scripting errors. Obviously this could be considered at least in part an issue for the writers of the Add-in - but rather it prompts:
***Enhancement for consideration***
I download large numbers of spreadsheets and documents from the internet (mainly statistics that are periodically updated and revised). It is often not possible to be certain whether a download will be relevant until after examining it, but the file gets added to the Recent Documents list in top spot.
If the document proves irrelevant on examination, ideally I want to purge it: close the file, delete it, and remove all reference in Recent Documents - in one operation (subject to confirmation to prevent accidental deletion through miskeying).
If the document does prove to be one I want to keep, I may need to rename it (as internet downloads aren't always given useful filenames), and remove the reference to the impenetrable name given to the original downloaded file from the Recent Documents list, replacing it with the new name. Again, a single operation.
Ideally, the Recent Document list needs slightly different organisation, more akin to a bookmark system, with group headings by topic for subfolders of files. Yes, this can be achieved by messing around with folder creation using the operating system, but that is a real pain compared with an instant popup menu as in a browser's bookmarks. That could easily allow for rapid access to several hundred documents.

Extended Recent Documents using History Master
Shows an extended Recent Documents list, with scroll arrows and a "Clear List" option. Ideally, "Clear List" should be replaced with "Manage List", with options to create bookmark type sublists, pin files to the list, delete files from the list (with a purge option to delete the files themselves rather than just the list pointer entry). Clearing the entire list would be an extreme option requiring confirmation, to avoid undoing a lot of work. IMHO this is vastly superior to the present Start offering.
I should point out that I tried to re-install the HistoryMaster Add-in, and re-downloaded it to verify that .xpi hadn't become corrupted.
looks like this is not a bug report but an enhancement request
Sounds like a valid enhancement request.
Note the fact in upcoming LibreOffice 4.3 you can selectively delete recent documents (see https://wiki.documentfoundation.org/ReleaseNotes/4.3#Start_Center_improvements).
I am currently using 22.214.171.124 under Win 7.
This seems to have allowed the recent files list to expand to 100 entries: however, after I reached that the list may have cleared automatically (I can't be 100% certain - only 99% certain that I didn't accidentally select "Clear list" - an option that really should be guarded with an "Are you sure?" box with "No" the preselected option).
Moreover, since that happened, I'm finding that the recent files list is not being updated in a consistent manner with the files I've opened, and even renamed and saved. They are simply not appearing much of the time. I am unable to deduce what distinguishes when a file is being added to the list, and when it isn't.
