For a long time, I have thought that Google Docs' UI has been too distracting -- so I made a simple theme that removes most of the distracting colors and borders!

Install it for yourself with Stylish:

.docs-companion-app-switcher-container.docs-material.docs-jfk-styling {
    display: none !important;
}
div#docs-editor {
    margin-right: 0 !important;
    width: calc(100%) !important;
}
.kix-zoomdocumentplugin-outer {
    background: white;
}
div#docs-editor {
    background: white;
}
.kix-paginateddocumentplugin.kix-paginateddocumentplugin-compact-mode {
    box-shadow: none !important;
}
div#kix-vertical-ruler {
    background: white;
}
div#kix-horizontal-ruler {
    border-bottom: 0px !important;
}
.goog-toolbar-separator {
    opacity: 0;
}
.docs-titlebar-button {
    filter: invert(100%);
    background-color: rgba(0, 0, 0, 0) !important;
    opacity: 0.5;
}

div#docs-toolbar-wrapper {
    border-top: 0px !important;
    border-bottom: 0px !important;
}
.goog-inline-block.docs-branding-icon {
    filter: grayscale(100%);
}
