* Improve activity startup time. We might be to rationalize dependencies a bit. Ensure that the startup animation is not slowing us down. Preload more modules inside rainbow. Import modules lazily where it make sense. '''(marco)'''

* 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. '''(benzea)'''

* 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. '''(marco)'''
