Hello. I only speak French, for other languages, it's Google.
I had deskscape 10: when I was in the wallpapers folder, where I had put my wallpapers, if I clicked on one of them, it immediately appeared on the desktop. Now, you have to go BEFORE through the options menu to do so. That is not very practical. Okay, there's a lot more we can do and I really appreciate it. But (this is an opinion that only engages me), we should review the ergonomics and by the way, the translation, which is confusing. Example: "change the background in order", I suppose that means, that the reading of the wallpapers, is done in the order of the display of the thumbnails, except that it does not do it , it continues in disorder.
An apply button, in different places, might also help.
I know I ask a lot, but I love this stuff.
See you.
