i really have enough of that stupid behavior that "show desktop" get completly reverted when you do *anything* afterwards - the whole purpose of "show desktop" is to get a ton of open windows minimized and bring a specific one in the forgeround - the current behavior makes the whole desktop unusable all day long
well, "show desktop" to rename a file in a folder-view reverting "show desktop" is just a joke and when the cursor still is there to rename the previously chosen file and you click the file get opened because folder-view no longer respects the "Open with double click" settings of the filemanager
P.S.: which upstream genie decided to come up again with the blue shadows around windows while at the same time remove the option to disable that which existed in KDE4? that's nice in the context "look how cool we are" but annoying and boring after a few days and it's diversionary
