Expand macro expanded/collapsed default state

Problem Definition

Expand macro collapses when the page is refreshed.
If the macro is expanded, once the page is refreshed, it returns to collapsed state, since it's the default configuration for the macro.

Suggested Solution

Add an option on Expand macro to customize its default status to be expanded or collapsed one the page is refreshed/opened.
Another possible solution for this case is to keep the current status - expanded or collapsed - on the macro when a page is refreshed.

Why this is important

If the page is too big, you need to find the expand/collapse link every time you access or refresh a page.

Workaround

None.
