I’ve used Deepin two years ago as my daily driver but abandoned it since there were some inconsistencies that irritated me at the time.
Now I’m playing with it on my second HDD, I have to say it has improved a lot!!! It is not only a pretty face but their in-house apps are working great.
I don’t know if the collaboration with Huawei has something to do with it, but it has matured. I’m really considering turning my daily driver into Deepin as my DE.
I noticed that too, but the filemanagers window can’t be themed, that has always been the case. I think it’s their philosophy to stay within the Deepin themes.
It’s not all deepins fault lol. I am not at a machine right now to explain further. They are usually harmless errors. One neat thing I learned just the other day. If you right click the deepin terminal icon there is a menu item called quake terminal which is a lot like yakuake.
