The highlighted state of this settings button looks a bit strange compared to the Eudic button next to it, and after clicking on "Go to Settings", this highlighted state does not disappear.

Looks awesome, I just got two issues:

1. The colour pattern of the switch button is in default, so it is blacker than the pin icon on the right, can we customize it to match the colour of the pin icon?
2. Do we want to add an option in settings to allow users disable the button or keep it there as an option

This settings button looks like bigger than other quick link button. May be you can use resizeImage make it better

   EZOpenLinkButton *button = [[EZOpenLinkButton alloc] init];
    NSImage *image = [NSImage imageWithSystemSymbolName:@"switch.2" accessibilityDescription:nil];
    image = [image resizeToSize:CGSizeMake(16, 16)];
    NSColor *tintColor = [NSColor mm_colorWithHexString:@"#C0C1C4"];
    image = [image imageWithTintColor:tintColor];
    button.image = image;

The color of the Settings button doesn't seem to match the color of the Google button next to it, what do you think about changing the TintColor to light blue? Or another suitable color.

I would personally prefer to keep it grey. Since blue represents selected in the pin feature, it could be confusing to make the icon blue.

Also, for users who don't enable the other icons, the grey one looks more concise as it fits the accent colour of the app.

Sounds reasonable, what do the rest of you think about this?

[phlpsong]

I think grey is better.

[AkaShark]

Agreed it!

[tisfeng]

Ok, let's keep it grey.
