Today I installed the metalscroll plugin on Visual Studio 2010. It works like a charm! It provides an overview of a long source code file with minimal screen space occupation, and offer the functionality to display markers for various purposes.
I highly recommend this wonderful Open Source freeware to any Visual Studio users. Here is the link.
The only disappointment for me is that it works with Visual Studio only… Is there similar plugin for other IDEs, especially Xcode & MonoDevelop?
