CPU History:
1.2:
- cmd-w doesn't close prefs window or about window: escape does
no known way to fix? map escape to cmd-w?
bugs:
- it counts CPUs from the bottom up. CPU 1 of 4 is the bottom, contrary to what I expected.
- make window snap to screen edges
see: MGSnappingWindow, also CPU Usage
- transparency for graphing window
hook up prefs to window setting
transparency of dock icon as well?
future ideas:
- a system to keep release notes synced and build a disk image with what I need?
- allow larger graphing window, a la Act Mon
- add a percentage text overlay like loadindock
Reference:
Mem -> CPU conversion key:
- wired = user
- active = sys
- inactive = nice
- free = idle

- is that how the current and last stuff is built? @done @project(CPU Mon)
- in other words, I need to pass the pointer by reference so I can modify its value (ie the memory it points to). keep in mind, someone has to clean up after the old memory. @done @project(CPU Mon)
