Don't try googling for how to expand your VirtualBox VM's drive image size. It will lead you to lots of out-dated, difficult instructions. Since VirtualBox 4.x, a new utility was added that really short-cuts the process of resizing drive images.
RubyMine is truly great for working on coding projects. However, new users soon discover that it lacks the ability to just open up new files to try something out real quick. Sure, you can create a new file easy enough. But, you have to name it and find a location within your project directory structure to save it before you can actually do some coding. Then after you're done trying that something out, you have to remember to go back and delete that file back out of your project. This is the common editor use case that the 'Scratch' plugin solves.
The Weather and Clock app icons should reflect current conditions just as the Calendar app's icon does. This would not take a lot of CPU and battery to accomplish. Also, the dynamic updating of an icon should be made available to all apps similar to badges and notifications. It could be managed as another notification type.
Next, the desktop launcher should allow these icons to be arbitrary sizes. This would facilitate the nice widgets functionality seen in android.
