Some ideas are not easy to discover; the concept of guided [[discovery]], where a mentor helps point a learner in a fruitful direction, can greatly accelerate the pace of learning. Some Sugar features are not easy to discover and while we are working to improve upon this, we provide some guides to discovery below.

No matter how well we do in making Sugar discoverable, there are necessarily some things that even a born lever-puller and button-clicker will not find easily, or will not understand fully. This page contains a list of such things, ranging from the almost but not quite obvious to the entirely opaque. We can consider whether some of these can be improved, but we know that there is a limit. So we have to alert teachers to these issues, and assist them to alert the children.

In Home View (hotkey F3), there are buttons to switch between the view of favorites in a ring and a list of all installed Activities. Select the star by an Activity to make it a Favorite. The hover menu for a Favorite includes the option to remove it from favorites without deleting it, and also an Erase option which deletes that activity!
