Today, manipulating states for some elements is a chore. Specifically, open/close for nav menus & dropdowns, active states for tabs & links, and more require navigating to the Element Settings panel, opening your menu/dropdown, and then navigating back to the Styles Panel. The same can be said for the 'Current' state for links; you can only manipulate this value by selecting a link which is directed to the current page.

My suggestion is simple; make these states easily accessible from a class level in the states menu. There's already a pattern for this as seen in checkmarks and radio buttons; the checked states dynamically appear in the states menu when manipulating custom checkmark values.
