X-Assist was created to assist in the much loved but missing features of OS 9 in OSX. Over time other helpful features have been added.
Application Switcher Menu (top right corner of screen) X-Assist has a Similar implementation.
Quick access to 'Recent Applications'. X-Assist has no 'limit'.
The ability to add personal hierarchies of items in an OS9-like 'apple' menu. X-Assist allows users to add any hierarchy into a 'Shortcuts' submenu.
An extensible 'Control Strip' like plugin architecture. X-Assist supports Objective-C (NSBundle) plugins. They are easy to write, and examples 'SetVolume' and 'MP3 Player' plugins are provided in this distribution.
OS 9 window behavior - when you switch applications by clicking in a window, all windows for that application are shown. This behavior has changed in OSX and can be a bit annoying. X-Assist brings back the OS9 windowing functionality and also allows you to toggle Between modes.
Easy access to System Preferences (Control Panels).
