This program allows users to assign priorities to processes with the Renice command. Higher priority processes get more CPU time and vice versa. The downside is that you have to use the terminal, and you have to know the renice syntax, process ID's, etc. Renicer is designed to run in the background, and automatically prioritizes whatever application is in front and it also ups the priority of the Finder, Dock, and Window Server. The program is designed to be simple enough for novices, yet flexible enough for the power user.
