Comment 1 for bug 1380987

The linked branch should optimize downloading a little, however, I'm having troubles to reproduce all the things. It seems to stay reasonably responsive here, even with all the pictures. Reading through the code I think we've done as much optimization to the images as we can. For example, we're caching images, only loading new ones from the network. Also when we download an image we're scaling it down for the preview in the notes list and saving that scaled down version to disk to not have to resize a second time.

Can you please test the linked branch and see if it behaves good enough now?
