On the subject of new backgrounds, I have gone through the list of backgrounds installed by default (on my system at least) and identify those that I think we should replace with new ones (already provided by Alex). The list is as follow:
1) To be removed/replaced: Appropriately Left Handed Blue-green crissocross Gold crickle Green curtain Kubical (because it shows 'KDE') Stripes Superfluous organ The good times Totally new product Triple gears Vegetative fog Water Won Ton soup
2) Other candidates for removal/replacement All good people Blue angle swirl Chicken song Geared globe Mystical right turn Time for lunch
The old backgrounds that will be removed/replaced will not be completely deleted. Instead they will be moved to tdeartwork/wallpapers/obsolete and installed into /opt/trinity/share/wallpapers/obsolete, so that a user can still access them if required. A note will be added to the v14.0.0 release notes.
Please review the list above and let me know if some changes are necessary (i.e. you want to add/remove wallpapers to the list).
Cheers Michele
