Add GNOME Theme Compatible.

[BenitzCoding]

You should add the compatibility for GNOME themes to modify things like the mouse cursors and the Windows buttons and also allow GTK 2 and 3 themes to work with the built in applications like settings, terminal, and file manager. Currently installing KDE and modifying it there doesn't allow the windows to work naively and gets reset upon restart, and doesn't change the buttons on applications like settings, terminal, and files. This can really help people like me who just want their computer to look like a mac.

Please implement this.
