In preferences there is a browser settings: "Use built-in" check box.

When you tap the browser icon near the link in the card, built-in (if "Use built-in" check box is set) or system browser (menu with all installed browsers) (if "Use built-in" check box is not set) will be opened with this link.

I want that long tap on the browse icon will do the opposite action that this setting: i.e open the link in system browser when "Use built-in" check box is set and the other way around.
