I participated in the Gran Canaria LibreOffice Hackfest recently, and once again, it was a great one :-) - I am looking forward to the next hackfest from the very minute I boarded the plane home.
As always, it was lots of talking to others, sharing ideas, plugging in the new people (few students appeared, and were interested - one even drew few dialogs in Glade, still need to integrate them). And the rest of the time, I was hacking - LibreOffice Start center again:
This time, it was the removal of files from the recent documents in the Start center; you can now point the mouse to the cross at the top right side of the document you want to remove from the list (but not from the disk of course!), a click - it is gone.
It will be available in LibreOffice 4.3; try the betas soon!
