Description:
sidebar showing a "mini-map" of a buffer
This package is an implementation of a minimap sidebar, i.e., a smaller display of the current buffer on the left side. It highlights the currently shown region and updates its position automatically. You can navigate in the minibar by dragging the active region with the mouse, which will scroll the corresponding edit buffer. Additionally, you can overlay information from the tags gathered by CEDET's semantic analyzer.
