Minor css snippet tweaks for Obsidian Minimal theme (dim non-focused pane, highlight sync icon). Works for Obsidian 1.2.8 (requires Electron v21 - Chrome 105+)

obsidian-minimal-theme-snippet.css

/* better contrast for status-bar */
.status-bar{
    color: var(--tx2);
}

/* better contrast for status bar (sync button) */
:is(.theme-light, .theme-dark) :is(.sync-status-icon.mod-success, .sync-status-icon.mod-working) {
    color: var(--tx2);
}

/* add a blinking highlight animation when syncing */
:is(.theme-light, .theme-dark) .sync-status-icon.mod-working {
    animation: color 0.25s infinite linear alternate;
}

/* use red color for failed sync */
:is(.theme-light, .theme-dark) .sync-status-icon.mod-error {
    color: var(--color-red);
}

@keyframes color {
    from {
        color: var(--tx2);
    }
    to {
        color: var(--ui3);
        filter: 
            drop-shadow(0 0 0.2px var(--ui3));
    }
}

/* dim editor that is not in focus useful for multiple tabs/panes */
:is(.theme-light, .theme-dark):has(.cm-focused) .cm-editor:not(.cm-focused) {
    background-color: var(--bg2);
    --active-line-bg: rgba(0,0,0,0.0);
    transition: background-color 0.2s;
}

/* specific for my use case - make image to be block display and always centered */
.internal-embed img:not([width]), .internal-embed audio, .internal-embed video {
    display: block;
    margin: auto;
}
