Just upgraded LibreOffice, and I normally runn Write and Calc pinned to the Win10 taskbar, with my "commonly used files" pinned to the taskbar icon right click popup.
But every time I update LibreOffice the old taskbar pins are invalidated - so I have to create new ones - and the pinned files list is of course empty on the new icons.
This is really quite annoying, especially as I forget to make a complete list every time I update...
The list of pinned items is easy:
%AppData%\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar
And the pinned files (jump list):
Please do something with this: I can't be the only person who is frustrated...
