You know I'm still "test-using" your Archdeepin iso, @ant . 
But like I told you before, I don't really like the accessory apps that come with deepin, so I use another file manager, terminal, text editor, music player, etc.
The deepin file manager annoys me in particular because it keeps trying to mount /dev/sda the minute I open it, and thus asking for my password. This is even though root/home partition is on /dev/sdb. I changed various settings in file manager to no avail.
I guess I just prefer using the apps I'm comfortable with. The desktop itself is fine, which is why I'm keeping it.
