That's more or less what I had in mind :-)

I noticed that as well. It is possible that a new list (with a different name) is now used. If that is the case and it does not require major changes, we should look at adding the new list as well when fixing bug 2093.

> BTW: is there a way to show all available wallpapers?
I guess that that may require some additional software. I haven't look at what the code does, but it seems that at the beginning 3 lists are downloaded (3 file transferring windows pop up on my screen) and those are probably used to populate the 3 tabs.
Provided that kde-look.org makes the list available (and I guess it does), we could write some code to let the user download the list of all wallpapers. The download could actually require sometime, so we should make it optional (perhaps an additinal button somewhere).
Please go ahead and file an enhancement bug report for this. In any case we will look at it after v14.0.0 is out.

Cheers
