I have been using KDE-Distros during the last 10 years. As it seems that the possibilty to identify easily the desktop I am just working on (with different Desktop pictures) will never come back for Plasma 5. The last LTS with this feature will be closed early next year and I need not to start an new OS on a second partition (not a problem, I always have up to 3 OS installed).
I believe your Desktop Program offers such a feature as standard. If that is so, can you tell me, which Distributions this feature works?
IK do hope to get soon a response from you. Thanks.
