Hi,
my list of activities is quite long and i miss a feature for grouping activities.
For example a group called “Play games”. If you push on that group button it shows something like a tree view with the activities “play PS3”, “play XBox 360”, “play Wii”, “play Wii U”. Or a group called “Internet” wich can contain "Amazon, Facebook, …).
A possibility for creating such activity-groups would be a nice feature.
