Deepin 15.4.1: problems with dde-file-manager and dde-dock, can anyone help?

Question

linux

Why does the file manager ignore the theme change and remain white with default window buttons? Is it treated somehow? And how to move the buttons to the left? Where is the dock file? - I want to trick him a little: add transparency, adjust the dimensions, change the color. I’ll make a reservation right away: I, an ordinary user, don’t know how to poke around in the source code, so I ask you to offer ready-made solutions like: open the terminal and enter such and such commands, or: the dock file is there - open and edit. Thanks in advance.
