Refreshing desktop looks comfortable
Search for Tweak (optimization) in the search bar, and you can see that there are several options in Extensions, where you can set the hidden desktop recycle bin and file management icons.
To hide the top status bar, you need to install the following plugin:
sudo apt-get install gnome-shell-extension-autohidetopbar
How to uninstall, just use remove
sudo apt-get remove gnome-shell-extension-autohidetopbar
After restarting the computer, enter Tweak->Extensions again, there is an additional option of Topbar, open it to complete the setting.
