	* We are using icons very extensively in the UI and we need a very efficient caching strategy. There are different possible approaches including caching on disk and in the video memory. It should not be hard to do better than we are currently doing, anyway. Drawing and animations performance should benefit a lot.

	* We are very often saving to the datastore unnecessarily and some times in concurrence with other heavy tasks (like switching activities). This is particularly bad on the XO given the compressed file system.

	* The current implementation of thumbnailing requires to take several screenshots of the activity window synchronously on basically every window stack change. Short term solution is to compromise on the accuracy of the screenshots to take them less often and improve performance. Long term we should look into using composition or gtk off-screen rendering to be able to take a screenshot even when the window is hidden/idle.		* The current implementation of thumbnailing requires to take several screenshots of the activity window synchronously on basically every window stack change.

	* Composition would help activity switching and the frame animation a lot. We cannot turn it on for all the windows for memory reason but it might be reasonable to composite the current active activity and the frame. It has a cost anyway, so we should see if we can improve drawing efficiency instead.		* Composition would help activity switching and the frame animation a lot.
