Great stuff. Here is some feedback.
I see there is now only one Check button, which checks both usage and partition. Ok, but the yellow notification bar for the partition flashes by too quickly. Not a big issue, since you can see the partition in the status bar.
The font for the status bar is too small to be read when minimized. I suggest increasing the font size, since there is space for that.
The Updated status bar seems to show the time when the Check button was pressed, not when the update was complete. Not a big problem, of course.
The Save button in Settings should perhaps make the settings window go away.
The Default button in Settings does not seem to do anything.
Also, the use external swap on boot setting seems to revert to on after updating Flopswap. Can this be helped, or the user notified after the update is complete (with a yellow bar or at least in the Description in HAM).
I wonder why you only use the left side of the screen in Quick Guide.
