As always, we really appriciate the help everyone gives us when testing new widgets. This is one of the biggest updates we've ever had, so we're calling on the MT masses to offer some feedback (and get to be the first to run iStat pro 4!).
The list of new features is massive (and we don't have it all ready yet), but here's a quick rundown on the more important ones:
New interface
It's now cleaner and much smaller than it was previously, while still maintaining the font size.
Bluetooth keyboard and mouse support
Drag and drop section reordering
Redesigned back
User manual
A fairly detailed overview of what's in iStat pro 4 and how to use it.
Keyboard shortcuts... lots of keyboard shortcuts
Listed below are all the keyboard shortcuts for iStat pro. Please note that the widget needs to be in focus before these will work (ie. you need to click on the widget once, or it needs to be the last widget you clicked last time you used Dashboard).
