The MetalScroll extension does not work with Visual Studio 2010. Since I have gotten used to its excellent scrollbar and selected-word highlighting, Visual Studio 2010 is nearly unusable without it.
There are two extensions which can partially reduce the pain of life without MetalScroll:
1. Enhanced Scrollbar
This ships as part of the Productivity Power Tools extension. Once installed, head over to Tools → Options → Productivity Power Tools → Enhanced Scroll Bar. Here select the Display Mode as Full map mode.
2. Highlight all occurences of selected word
Yes, that is the name of this extension which can be downloaded here. Install it, and double-click any word to see all of its occurences in the file highlighted in green color.
There are a few ways in which these extensions still lag behind MetalScroll:
MetalScroll could display all occurences of the selected word in the scrollbar too (in addition to the editor view). This was really useful to look at and jump to occurences that are many screens below or above the current occurence.
The highlighting of the selected word should persist. With the above extension, the highlighting disappears if I merely single-click in the editor window.
Tried with: Visual Studio 2010, Productivity Power Tools 10.0.20626.18 and Highlight all occurences of selected word 1.31
