When editing really long code blocks (which should definitely be refactored anyway, but that\'s beyond the scope of this question), I often long for the ability to collapse
You can collapse specific blocks of text within visual studio, but you have to turn off automatic outlining.
Right click in your code window and select (Outlining | Stop Outlining)
Then, select some text, right click and select (Outlining | Hide Selection)
When you turn on automatic outlining again, your custom "Regions" will no longer collapse.
