Ability to 'Expand All' or 'Collapse All' for Expand Macros on a page

Problem Definition

Currently Expand Macros need to be expanded individually. Search function such as CTRL+F or CMD+F doesn't search within collapsed Expand Macros.

Suggested Solution

Provide ability to Expand All (or inversely, Collapse All) with one click so they can be searched.

Why this is important

It prevents the user having to expand all individually which can take a lot of time.
