AltSwitch is an advanced Alt-Tab replacement. AltSwitch lets you easily navigate between tasks running on your computer using keyboard and/or mouse, mouse wheel supported as well. For each task small preview image is displayed, size of the preview image is adjustable. Task preview includes all task windows, even those that are floating palettes. Previews are caching for faster drawing.
There are two different styles of task preview - Fit and Desktop. If the Fit style is selected, task preview is zoomed or shrunk to fit the size of the preview area. If the Desktop style is selected, task preview is looks like a screenshot of the entire desktop. AltSwitch optionally draws performance information for each task in real time. This information includes processor and memory usage displayed as two bars.
