I suppose it could be a good idea, but it should provide something different from Alt-Tab in Windows to avoid reinventing the wheel. How about the possibility of change between all apps currently running, including those which reside in the system tray? I know some task managers currently provide this functionality, showing all windows "drew" by Windows, and allowing to bring to the front those which are hidden, including app in the systray. And it could be even better if it showed thumbnails of the software! (tricky)
Also, another suggestion. Some of these aliases are interesting, so I vote for merging the most useful in the main FARR installation, or provide an "alias" page to complement the future "plugins" page for FARR.
