The crew over at iSlayer have been busy releasing major updates to their killer system monitoring widgets, and not a moment too late for this year's Apple Design Awards (entry deadline is April 23rd). Earlier this month we missed a major upgrade and UI overhaul to iStat nano, bringing the compact system monitoring widget to v2 and adding a ton of new features.
With the release of what almost looks like an all-new version of iStat pro v4, however, iSlayer has brought a consistent, uniform UI to both widgets. While I agree that you should probably sit down and take a deep breath before reading through the extensive list of changes, the big-hitters include: support for the battery meters in bluetooth keyboards and mice, instant update for things like network changes and disk mounting, a choice between memory and CPU usage in the process panel, as well as drag and drop re-ordering of sections inside the widget, allowing you to customize the layout to your heart's content.
That isn't all though - go check out the huge list of changes for either of these widgets and consider showing iSlayer some donation love for all the stellar work they've done on two of the inarguable kings of system monitoring widgets for Mac OS X.
