Yesterday I wrote about map mode, an exciting enhancement to Visual Studio 2013’s vertical scroll bar. If you haven’t enabled the feature yet, go do it, I’ll wait.
If you had the Productivity Power Tools extension installed prior to enabling the feature, you may have noticed that there are some extra annotations in the scroll bar. These annotations, shown in the form of vertical lines and “bubbles” illustrate scope and nesting level.
You can control whether these annotations are displayed by changing the “Show code structure in the margin” setting under Productivity Power Tools/Other extensions in the options dialog. So far, I think they’re pretty helpful so I plan on leaving them enabled; at least for a while.
