It’s about the “Document history” feature. If you enable it to be shown on your KDE taskbar, you’ll notice one interesting feature which I find quite annoying: while it lists the pre-existing documents I’ve recently looked up (or even mistakenly clicked on) – which I could honestly do without – it doesn’t show any documents I’ve recently created and worked on – which to me are central and essential. At least, this is true of Open Office Writer documents, I’m not sure about other types of documents. Now, don’t you agree that it would make more sense to at least show both? After all, people do tend to care about documents they’ve created, right?
I do not think that OpenOffice is that much integrated in KDE (OO has btw its own ‘recencently opened’ feature).
I also think that you better ask for a new KDE feature in de KDE Bug tracking System: https://bugs.kde.org/.
I think you’re right… although they’ll probably just tell me to use koffice instead…
As far as I can remember KDE has never tracked every document you open; so I don’t think this is new.
Both OO and KWord show the last ten documents in the menu.
Some KDE applications, e.g. KPDF, that do not have a ‘Recent files’ menu entry will show you a list of recent documents if you hold down ‘Open’ rather than simply click on it.
